D2- Chromosome 9 DNA Traced to 1600s Chamberlains

The Chamberlain Story has traced a piece of DNA on chromosome 9 back to one of the parents of Thomas, Edmond and William Chamberlain. These three  brothers immigrated to America in the 1600s. My results (DC) on 23&me show that I share this piece of DNA with my uncle RC and six distant relatives TC, CS, DB, MS, CB and DP.

The eight individuals initialed above share part of chromosome 9. When two or more share an identical chromosome segment, they inherited it from a common ancestor. The three Chamberlain brothers of Middlesex County Massachusetts shared this same DNA in the 1600s. Apparently, all three brothers inherited this DNA from one of their parents. Genealogical information has confirmed that DB is a descendant of Thomas, CS of Edmond, and DC and RC are descendants of William.

23&me Advanced DNA Comparisons

The following diagrams from 23&me- Family & Friends- Advanced DNA Comparisons show that six individuals share a common ancestor. That ancestor is one of the parents of Thomas, Edmond and William Chamberlain. None of these six share any other DNA and therefore all are very distant relatives from one another, (6th to 12th cousins).

Figure 2. CS, a descendant of Edmond Chamberlain, shares DNA from this part of Chromosome 9 with DC, DB, MS, CB and DP

Figure 3. DB, a descendant of Thomas Chamberlain, shares DNA from this part of Chromosome 9 with DC, CS, MS, CB and DP

Figure 4. compares DC (purple) and my uncle RC (red), where our DNA matches with TC. RC is my father’s brother and therefore, our matching segments on chromosomes 1 and 9 come from my paternal line.

Figure 4. TC compared to DC and RC (me and my uncle), and CS, DB and MS

TC is another distant cousin. His genealogy information is not available. However, his surname, Chamberlain, gives us a great clue.

In addition to chromosome 9, TC also shares with us DNA from chromosome 1. This shows that he has a closer genetic relationship to me (purple) and my uncle RC (red), than CS (orange), DB (blue) and MS (green).

Therefore, we know he is also a descendant of William Chamberlain.

Chromosome 9 match could yield new information

The other three individuals, MS, CB, and DP have no available genealogy information. Nevertheless, they are almost certainly descendants of one of the three Chamberlain brothers.

However, other possibilities do exist. For example, if we can trace the chromosome 9 segment directly to England, we may learn more about the origin of our Chamberlain family. And, what if it were traced to the pre-1800s Chamberlains of Virginia? This might prove that Francis Chamberlain is the father of Thomas, Edmond and William.

Chamberlain family and Chromosome 9

Figure 5. shows DNA of my various family members as they match with our uncle RC. I use my uncle as a control to be sure we are looking at our paternal DNA. Chromosome 9 in figure 5 shows my full segment (purple). There is about a 50/50 chance to pass this segment of chromosome 9 on to each child in the next generation.

Chromosome 9 is about 138 million base pairs in length, (138Mbp.) The piece of chromosome 9 which I inherited from William Chamberlain is about 57Mbp. It seems amazing that such a large strand of unbroken DNA survived nine generations between myself and William.

I passed on the complete segment to my daughter LC (blue). My brother EC (orange), however, did not receive any of this special piece of DNA from our father, and my sister DG apparently received a very small portion.

The red on chromosome 9 shows that TC also has the DNA from William. The red on chromosome 1 is the only other piece he shares with our immediate family. Therefore, I estimate that TC is our fourth or fifth cousin.

Why chromosomes pass from generation to generation in chunks

Figure 6. Meiosis begins with two homologous chromosomes. These come together, crossover occurs, and cells divide twice to form haploid gametes with a recombination of DNA.

We all have 23 chromosome pairs. One half of each pair (a chromatid) comes from our mother the other half from our father. Therefore, we all have 46 chomatids. In normal cell division these 46 chromatids independently duplicate themselves into homologous chromosomes. They then separate into two genetically identical cells.

However, germ cells or gametes are formed by a process called meiosis. This begins with two homologous chromosomes. For our purpose we might say the blue is chromosome 9 from the father and the pink is chromosome 9 from the mother.

In meiosis, these come together where crossover occurs, causing a recombination of DNA. The cells then divide twice to form haploid sperm or egg cells.

Crossovers occur with greater frequency in some areas of the chromosome than in others. Therefore, certain chunks of the chromosome tend to be passed down from generation to generation.

What are the odds?

There was only about one chance in 500 that the Chamberlain chr9 DNA made it all the way from William to me. How lucky is that? However, this segment is only about .5% of William’s DNA. Therefore, the chance that some part of his DNA might make the nine generation journey to me is roughly 40%.

Nevertheless, the Chamberlain chr9 segment got off to a good start.  Since all three brothers apparently received it and they all had many children who could carry it along to future generations.

The various pathways of the Chamberlain segment of chromosome 9 are shown in the next three sections. More detailed information on the children of Thomas, Edmond and William can be found in Chapter 4.

Chamberlain Chr9 first five generations from Thomas

Generation 1- Thomas Chamberlain1 was born in England about 1615 and immigrated to Virginia in 1635.  There he met his wife Mary Parker who arrived from England the same year. They were forced to leave Virginia in 1644. Thomas was made a Freeman in Woburn, Massachusetts on May 29, 1644. They had four children, Thomas, Anna, Mary and Samuel. Mary died 20 December 1669 and Thomas remarried the twice widowed Mary Jones Poulter Parker 16 April 1674. He had no children with his second wife.

Generation 2- Thomas Chamberlain was born in Virginia about 1639. His baptismal record in 1655 at Chelmsford said he was about 17 years. He married Sarah Proctor, the daughter of Robert Proctor and Jane Hildreth Proctor in Chelmsford, Massachusetts on August 10, 1666. They had eight children, Thomas, Mary, Dorothy, Samuel, John, Jane, Elizabeth, and an unidentified baby.

Abigail was born 26 December 1683 in Billerica, Massachusetts, the daughter of Nathaniel and Elizabeth Hill, and died 16 May 1760. Samuel and Abigail had 11 children: Benjamin, John, Abigail, Elizabeth, Jonathan, Samuel, Joseph, Thomas, Jane, Aaron, Jacob.

Generation 4- Elizabeth Chamberlain was born 8 January 1710 in Chelmsford, Massachusetts, died about 1760 in Concord. She married Timothy Fletcher 15 April 1726. Timothy Fletcher was born 28 August 1704 in Concord and died 1779 in Chelmsford. They had ten children: Elizabeth, Timothy, Sarah, John, Joseph, Benjamin, Ephraim, Lydia, Joel and Samuel.

Generation 5- Ephraim Fletcher born 5 February 1740. Enlisted 30 July 1778 in the Revolutionary War, Rhode Island campaign. Died 1 January 1831. Married Sarah Davenport in Grafton, Massachusetts December 7, 1762. Sarah was born 1 October 1739 in Shrewsbury, Massachusetts. Died November 4, 1806 in Newport, New Hampshire. Ephraim and Sarah had nine children: Joel, Sarah, Ephraim, Amos, Mary, Lydia, Timothy, Anna and Benjamin.

Chamberlain Chr9 first five generations from Edmond

Generation 1- Edmond Chamberlain2 was born in England about 1617. He married Mary Turner on 4 January 1647 in Roxbury, Massachusetts. His wife Mary died at Roxbury 7 October 1669. Edmond Chamberlain Sr. married his second wife, the 35-year-old widow Hannah Witter Burditt 22 June 1670 at Swampscott, Connecticut.

Edmond was the constable of Malden, Massachsetts in 1675 during the King Phillips Indian War. His 19 year-old son, Edmund Jr. died that year in the “Great Swamp Fight”. Edmond Sr. died 8 May 1696 and Hanna a few weeks later on July 28, both in Woodstock, Connecticut. He is buried there near the First Congregational Church.

Edmond and Mary had seven children: Mary, Sarah, John, Elizabeth, John, Edmund and Jacob. Hannah had six children from her first marriage to Thomas Burditt: Thomas, Mary, Hannah, Joseph, Sarah and Ruth. Hannah then had five more with Edmond Chamberlain: Susanna, Ebenezer, Susanna, Edmund III and Mary. This was a total of eighteen children in their blended family. However, many of the children died and their name was given to the next gender appropriate child. There were two Johns, two Susannas, three Marys and two Edmunds. When Edmund Jr. died in the Indian war on December 19, 1675, he was replaced six weeks later when Edmund III was born.

Generation 2- Edmund Chamberlain III was born on January 31, 1676 at Windham, Connecticut. He married Elizabeth Bartholomew 21 November 1699 at Woodstock, Connecticut. He died 18 December 1751 at Woodstock. She was born 15 March 1674 and died 28 December 1746 also at Woodstock. They had eleven Children: Jacob, Edmond IV, Elisabeth, William, James, Joseph, Samuel, Peter, John, Mary, Sarah and Hannah.

Generation 5- Elisha Chamberlain born 30 March 1768, died 11 September 1841. Married Sarah Chandler about 1796 in Connecticut. She was born 17 July 1773, and died 27 May 1833. Children of Elisha and Sarah: Sally, Nathan, John Chandler, Joshua, Mary, Lydia, Moses, Nancy.

Chamberlain Chr9 first five generations from William

Generation 1- William Chamberlain was born in England in about 1619 and came to America at age 16 in 1635, he died 31 May 1706 in Billerica, Middlesex, Massachusetts. Married Rebecca Addington or Shelly3 4 January 1646 at Roxbury, Suffolk, Massachusetts. Rebecca was born in 1625 at Cambridge, Middlesex, Massachusetts, and died in Cambridge Prison 26 September 1692. It is believed she was accused of witchcraft. Children of William and Rebecca: Tmothy, Isaac, William, John, Sarah, Jacob, Thomas, Edmund, Rebecca, Abraham, Ann, Clement, Daniel.

Generation 2 Daniel Chamberlain4 was born in 1671 Billerica Middlesex, Massachusetts, d. 22 November, 1725, Billerica. Married in 1694, Billerica, to Mary Swain 1673-1713. Children of Daniel and Mary  Isaac, Ebenezer, Ephaim, Thomas, Mary, Dorothy.

Generation 3- Thomas Chamberlain was born in 1703 in Billerica, MA and married Abigail Pierce 10 June 1730 in Concord, Middlesex, MA.5 She was born 18 May 1706, Woburn MA, died 18 may 1769, Westmoreland, NH. (Note: I have done extensive research to get correct information and birth order of their children.) Children of Thomas and Abigail:   Josiah, Isaac, Joshua, Job, Jedediah, John and Increase and Abigail.

Generation 4- John Chamberlain was born about 1739 in Newton, Middlesex, Massachusetts.6 His father Thomas moved from Newton to Westmoreland which places John’s birth order between Jedediah and the youngest brother Increase. John married an Indian we know as Winona. This John Chamberlain is the father of Spencer Chamberlain. To see the complete and complicated evidence for this, read Chapter 10 and Chapter 15.

Generation 5- Spencer Chamberlain was born about 1786 in Westmoreland, Cheshire, NH. Died 21 December 1853 in Glover, Orleans, VT. He married Millie French in Glover, VT. She was born on 28 March 1786 and died 21 September 1849. Spencer Chamberlain is known as the hero of Runaway PondThe children of Spencer and Millie:  Jeanette, Amanda, Delana, Alonzo, Sarah, Melissa.

D1- The Chamberlain’s in America Y-DNA Link to William de Tancarville.

Three predominant Chamberlain families immigrated to America in the 1600s. These were the 1- Thomas, Edmond, William Chamberlain, presumably brothers; 2- Henry Chamberlain, known as the Black Smith, and 3- Richard Chamberlain of Braintree, MA.

Y-DNA tests show that these three families are unrelated. However, in my study of the Y-DNA data, I have found that in these three divergent lines of the Chamberlain family, at least two can be traced back to a single source. According to history, this might be the family of Lord Chamberlain to the Duke of Normandy and to King Henry I of England, William de Tancarville.

The origin of the Chamberlain surname

In January 1066, King Edward on his death bed granted the kingdom to Harold Godwinson, the head of a very powerful noble family in England. When the king died, Godwinson was proclaimed King Harold II. On the other side of the English channel, William Duke of Normandy was outraged.

Fifteen years earlier, William visited England and met with his cousin King Edward. According to Norman historians, the childless English King promised to make William his heir to the throne.

William was of Viking origin. The Vikings pillaged northern France in the late ninth and early tenth centuries. However, they eventually accepted that their territory of Normandy become part of France in exchange for peace. William and other Normans were descendants of these Scandinavian invaders. They grew up in Normandy loyal to the French kingdom.1

The Battle of Hastings 1066

On September 28, 1066, William, determined to have the promised throne, landed with thousands of troops and cavalry on Britain’s southeast coast. He seized the village of Pevensey.  He then marched on to Hastings where he paused to organize his forces.

King Harold soon arrived near Hastings with his army. The day after his arrival, October 14, 1066, William led his forces in to battle. It ended in a decisive victory. Harold was shot in the eye with an arrow and died and his forces were destroyed. After his victory at Hastings, “William the Conqueror” marched on to London which submitted to his army. There, crowned on Christmas day in Westminster Abbey, he became the first Norman king of England.

William and other Normans spoke French which became the language of the king’s court. It gradually blended with the Anglo-Saxon tongue to give birth to modern English.1

Tancarville Castle, Normandy

One member of the King’s court was Count William de Tancarville of Tancarville Castle. His castle was built on a spur overlooking the Seine River in Normandy. He came with “William the Conqueror” to England.  Though he returned to Normandy himself, his sons and descendants remained in England and occupied lands granted to them. William de Tancarville “is the progenitor of the Chamberlain family in England and America.”2

“John de Tancarville, son of the former Earl, was Lord Chamberlain to King Henry I”.2 Henry ruled England from 1100-1135. John “assumed his title as a surname. Richard, son of John, was also Chamberlain of King Steven and the surname Chamberlain has since his day been that of the family.”2

Famille de Tancarville

An English translation of a French record of the Tancarville family gives us a different version of the story. It is more detailed and therefore may be more accurate. It tells us that Guillaume de Tancarville (the French name for William) was the chamberlain to King Henry I.

Le Chateau Fort de la Tancrede, Picture from 1950s

Translation: “William I de Tancarville son of Raoul, chief chamberlain of Normandy and Angleterre. It seems certain that he was the chamberlain of Duke Robert Curthose, and his brother Henry Beauclerc, after his victory at the Battle of Tinchebray (1106). He was a close adviser to King Henry I of England.”3

When William the Conqueror died his oldest sons inherited the kingdom. Duke Robert Curthose ruled Nomandy and his brother William Rufus became King William II of England. Their younger brother, Henry Beauclerc, became King Henry I of England in 1100 when William II was killed in a hunting accident. Henry defeated his brother Robert for the control of Normandy in the Battle of Tinchabray.4

Rabel de Tancarville, the son of William, inherited the role of chamberlain of Normandy from his father. He refused to recognize Stephen as King of England for unknown reasons but quickly submitted. Therefore, apparently, King Steven confirmed him in his function as chamberlain.3

This French account gives us three successive chamberlains to the Duke of Normandy, Raoul, William and Rabel. The English chamberlains, John and Richard, are not mentioned in this report.

Do most Chamberlains descend from William de Tancarville?

About 100 living Chamberlain male descendants (mostly in the United States) were Y-DNA tested before 2011. Modern Chamberlain genealogist James Baldwin Parker concluded that the results of these tests  “absolutely proves that there are more than a dozen Chamberlain ancestral lines in the States and elsewhere who are completely and totally unrelated to one another. Only one of them, if any, could be a Tankerville line.”5

The Y-DNA data shows that the Chamberlain families tested are very diverse. That is certainly true. However, I am not sure what this proves and what it does not prove. The data just hasn’t been studied thoroughly enough to come to any conclusions.

Therefore, I decided to examine the Y-DNA data. I would like to find answers to a couple of interesting questions: Are any of these diverse Chamberlains related in their paternal line? And, how many of these Chamberlain families, if any, can be linked to William de Tancarville and his family?

Y-DNA genetic analysis

We all have 23 pairs of chromosomes. We receive one set from our mother which is paired with another set we receive from our father. One of these pairs, the X and Y chromosomes, are sex chromosomes which determine gender. Those with two X chromosomes are female. While males always receive an X chromosome from his mother and a Y chromosome from his father.

23 pairs of chromosomes of the human genome

Mutations in genetic markers called STRs (short tandem repeats) are used to track genetic diversity in father to son generations

When a mutation occurs in the Y-chromosome, it will also be passed on to future male progeny giving that line its own trademark.

This information can be used for many purposes including the following:

1- To identify for an individual their own Chamberlain or non-Chamberlain paternal ancestor lineage.
2- To estimate the number of different ancestral lines that exist among Chamberlain families through out the world.
3- To trace known USA Chamberlain lineages to common ancestors and locations in England or other countries.

Modern Chamberlain family groups

Twenty four males with Chamberlain surname were included in a Y-DNA analysis by the Chamberlain Association in 2003. Twelve of these entries were from the Thomas, Edmond, William (TEW) family. My brother, Ernest Martin Chamberlain, Jr., was included in this data. Our family ancestor in this article is identified as Spencer Chamberlain 1786-1853 (William).

Thirty-eight additional subjects were selected from an unsorted Chamberlain surname project FamilyTree DNA chart.6 I selected only entries that identified an ancestor and which tested 25 STRs. The STRs are identified in my report with numbers 1 through 25.

All 62 tests were evaluated and divided into families.  I consider tests with 3 or less mutation differences to be the same family. There are 23 families. They usually had only 0-2 STR differences. After sorting, I assigned each family an identification letter, A through W.  The Thomas Edmond William family (family A)  was the largest with 18 individuals. The Spencer Chamberlain branch is A013.

Y-DNA Spread Sheet gives a brief ancestor description from all of the 62 Chamberlains who are organized into 23 familes. It shows the Y-DNA profile for 25 STRs for each individual.  Also, genetic divergence (the average number of different STRs) is evaluated within the TEW family and also compared to to other families.

A key to identify the letter assigned to each family and the names of the 25 STRs is also given in the Y-DNA spread sheet.

A unique allele in Thomas, Edmond and William Chamberlain’s American family

The TEW family has a unique allele not found in any of the other 22 families, STR 21, allele 32. This may be very helpful in identifying relatives of the three brothers in England and other countries.

In my own family line, one mutation occurred in one of the nine generations between William Chamberlain and Ernest M. Chamberlain, Jr. (STR 24, allele 17) This could help us identify close relatives in the United States on our paternal line.

Finding the Y-DNA profile of the common paternal ancestor (CPA) of related families

Some individuals tested from the TEW family have no changes in their STRs. In other words, they have the same Y-DNA profile as their common paternal ancestor (CPA), Thomas, Edmond or William. Variance from the CPA was 0, 1 or 2 for each of the 18 individuals tested. The average divergence score through the generations since the brothers emigrated to America was 1. The average mutations in the Henry Chamberlain family from their common male ancestor was 1.8. 

It is helpful to know the most likely Y-DNA profile of the CPA of various groups of related families. The likely profile was calculated for each group by counting and selecting the majority allele in each of the 25 STRs. In a case where there is an equal number, either choice will result in the same score. Example: In STR 12, in B- Henry above, if  either allele 17, 26 or 27 is chosen for the CPA, the average will still be 1.8.

My goal is to separate out all families unrelated to the paternal line of William de Tancarville. This should lower the divergence average as much as it is possible. When all unrelated families are removed, the common paternal ancestor profile should be very similar to that of William de Tancarville.

Separating out unrelated families

Some families will not be related to the Tancarvilles on the paternal line. In many cases, lines directly descending from the Tancarvilles may have passed on the surname though a female relative, or through an adopted male heir. Therefore, the Chamberlain name was passed on, but an unrelated Y-DNA family was formed  Also, some unrelated families may have independently assumed the name of Chamberlain.

To separate the unrelated paternal lines, my first thought was to match the STRs of each family with those of all other families. Their scores, averaged and sorted, might separate related from unrelated families. If these differences were great enough, I thought, two distinct normal (bell curve) populations would be formed.

In the diagram below, each of the 23 families is represented by a letter. The number of different STRs between each family is presented. The averages when sorted ranged from 9.5 to 19.2. (A key to family identification for each letter is found in Y-DNA Spread Sheet)

Charting the distribution of the average scores shows a definite separation of three families from the other 20. I then checked the average number of mutations from the estimated profile of their common paternal ancestor (CPA) for the remaining 20 families.

The average number of mutations from the common paternal ancestor is now 6.8. This is down from the 8.3 average for all 23 families, but it is still much too high. Generations from William de Tancarville to the present should be approximately 2.5 times that of the early American immigrants. Therefore, compared to the average of TEW or Henry reported previously, the Tancarville average should be between about 2.5 and 4.5.

Another diagram was designed to visually observe how close or how far each family is related to every other family. Letters assigned to the various families are shown at the end of the diagram. Each family is compared to every other family. Low scores on the scale of 5 to 15 show families that are likely related. High scores show which families can not be related.

Observation of this diagram shows that seven families C, D, M, P, Q, R and S are completely unrelated. All of the families were sorted and the unrelated families (non color coded letters) appear on the bottom third of the chart. This lower third of the diagram shows that none of these families (uncolored letters) are found in the green (likely related) section, but many letters are deep in the orange and red (not related section).

The seven unrelated families were removed and a CPA Y-DNA analysis was done on the remaining 13 families.

Analysis of the 13 remaining families lowered the average to 5.5. However, this is still too high. Further observation of the spread diagram shows that in the 13 families, there are two independent groups.

Group 1 contains families A, B, E, F, N and W. These, after sorting, were placed in the top third of the diagram and colored blue. Fourteen of the “blue” families are in the “likely related” section when compared with other “blue” families. However,  there are sixteen “yellow” but no “blue” families which fall in the orange “probably not related” section of the chart.

On the other hand, Group 2 “yellow” families show that 18 are “likely related” to other “yellow” families.  While no “yellow” families, but 15 “blue” families, are “probably not related” to other “yellow” families. Families G, H, I, J, K, L and O are in Group 2. (Key to family identification for each letter is in Y-DNA Spread Sheet)

Separating the two groups of unrelated families again lowered the average mutation changes from the CPA. The CPA Y-DNA analysis for Group 1 average was 4.5, and for Group 2 it was 4.7.

Conclusions

Sixty-two Chamberlain males tested for their Y-DNA analysis were grouped into 23 families. Members of the three American families who immigrated in the 1600s have three or less STR changes in their Y-DNA profile.

Ten of the 23 families, C, D, M, P, Q, R, S, T, U and V are completely unrelated in their paternal line, based on their Y-DNA profile. However, it is highly likely that two groups of paternal families originated at about the time of the chamberlains of Normandy and England.

Thirteen of the families form two unrelated groups.  Group 1, families are A, B, E, F, N and W; and Group 2, families are G, H, I, J, K, L and O. Both of these groups have one family with ancestor ties to France. (Group 1 family W, and Group 2 family  J) Y-DNA data shows that family members of one, but not both, of these groups could be the direct line father-to-son descendants of William de Tancarville.

Hereditary Office of Chamberlain

The family of Tancarville was of Norman stock, of likely Scandinavian decent, originating from the Viking Tancredus (fr. Tancrède). Tancrede was a companion of Rollo in the Norman conquest of northern France. His progeny was closely tied to the royal family and became the hereditary Chamberlain’s of Normandy and of England. The family was known as being, “in the highest ranks of the Anglo-Norman aristocracy, the lords of Tancarville”Tancrede founded and gave his name to the castle fort built on a cliff overlooking the Seine.

Tancarville Castle

Raoul fitz Gerald le Chamberlain (c. 1008- c. 1080) was the son of Gerald II and Helisende. His was the earliest known use of the patronymic “FitzGerald”. Raoul was an Officer of Duke Robert the Magnificent and commanded his fleet in 1029.  Duke Robert placed his young son William in the trusted care of the Chamberlain’s household. Thereby, William (the future conqueror of England), was nourished, protected and educated in the skills of knighthood while in their gaurdianship.8

Guillaume I de Tancarville (c. 1045-1129) “le Chamberlain de Normandie et England”. Guillaume, son of Raoul and Avice, was the first to use the Tancarville name. He may be better known by the English version of his name – William de Tancarville.

Rabel de Tancarville (c. 1080-1140) “le Chamberlain de Normandie et England”. Son of Guillaume I and Maude d’Arques. Rabel de Tancarville remained the only chamberlain-in-chief of Normandy and England until Henry I of England created a separate hereditary office for England in 1133,9 and entrusted it to Aubrey (II) of Vere and his heirs.10

A second family held the office of Chamberlain

Aubrey de Vere II (c. 1085 – May 1141) was the eldest surviving son of Aubrey de Vere and his wife Beatrice. He may have been Norman, possibly from the region of Ver in the Cotentin peninsula of western Normandy.

Aubrey II served as one of the king’s chamberlains under Kings Henry I and Stephen. In June 1133 King Henry I awarded the office of Master Chamberlain to Aubrey and his heirs. His eldest son, Aubrey de Vere III, later was made Earl of Oxford. His descendants held that office and title which in later centuries was known as Lord Great Chamberlain until the extinction of the Vere male line in 1703.11

The ten known children of Aubrey II and his wife Adeliza include five sons and five daughters. It is unknown if any of these families took on the surname of Chamberlain.

Château De Tancarville – A Story Of Heritage In Danger

The website Normandy Then and Now recently published an article about the sad condition and need for restoration of the Chateau De Tancarville.

“The story of the château cannot be over, but now while it has stalled the buildings deteriorate and ancient carvings are lost. There are no longer open days, once hosted by the passionate local historical association.  Doors are padlocked.”

“Château de Tancarville was registered as an historic monument in 1862. Pierre Bortolussi, architect from the department of Historic Monuments is still waiting to hear from any firms employed to undertake the renovations.”

“We look forward to the day when we match our postcard of château de Tancarville and tell the full history of this fascinating place.12

An ancient abandoned complex, viewed through padlocked gates, will chateau de Tancarville survive to open again?
