If you are from the broader UK, Commonwealth, or a former colony with any antecedents from the UK, the odds are still good that you are also at least a third cousin of Richard III. The populations of several other European countries are also home to many, many cousins of Richard III, particularly Spain and Portugal, wherein lay the marital destinies of some of his female third cousins. If you are in the west but not of western ancestry, over time, your relatives or descendants will very likely marry a third cousin of Richard III.
How is this possible?
Andrew Millard, a genealogist in Durham, UK, has attempted to calculate "the probability that a present-day English person descends from Edward III." Millard's conclusion is that the probability is well over 99%. As Edward III is the 2nd great-grandfather of Richard III, the odds are you have an ancestral line that runs straight through one of Edward's other great-great-grandchildren, all of whom were third cousins to Richard III.
However, the question remains how many generations removed you are from that point. Benedict Cumberbatch, for instance, is his third cousin, 16 times removed.
You may also have a closer than third cousin relationship to Richard III, as he had nieces and nephews, first and second cousins, with lines surviving to this day. And, he has many lines of cousins that descend from his great-great grandparents other than Edward III (in fact, his maternal line 2nd great grandmother, the mother of Katherine de Roet Swynford, is not even known, so anything is possible).
In fairness, the University of Leicester is claiming only one to 17 million people have connections to Richard III. However, they are not indicating how their probability calculations vary from Millard's (and they may not be familiar with his work). In the days leading up to Richard III's interment, and as his burial site in Leicester becomes a tourist attraction, considering these connections can make history very tangible, universal, and personal.
Richard III's nieces and nephews (who had children)
Richard is, infamously, a suspect in the deaths of two of his nephews. However, several of his other nieces and nephews had children with descendant lines surviving to today. Eight of his nieces and nephews, many times removed, were reportedly involved in the legal dispute over whether he would be interred in York or Leicester. His living nieces and nephews descend from the legitimate and illegitimate children of his siblings who are known to have had offspring:- Anne St. Leger (14 January 1476 – 21 April 1526), who married George Manners, 11th Baron de Ros
- Michael Ibsen is in this line in a completely female descent (which means he carries the mtDNA of Richard), but there are also may who do not follow a single-sex descent line
- Elizabeth of York, queen consort to Henry VII of England (11 February 1466 – 11 February 1503)
- Queen Elizabeth is niece of Richard III, 16 times removed, through this line (Margaret Tudor>Margaret Douglas>Henry Stuart, Lord Darnley>James VI>Elizabeth Stuart, Queen of Bohemia>Sophia, Princess Palatine>George I>George II>Frederick, Prince of Wales>George III>Prince Edward, Duke of Kent and Strathearn>Queen Victoria>Edward VII>George V>George VI>Elizabeth II)
- Cecily of York (20 March 1469 – 24 August 1507), married first John Welles, 1st Viscount Welles and second Thomas Kyme or Keme
- Anne of York (2 November 1475 – 23 November 1511), married Thomas Howard (later 3rd Duke of Norfolk)
- Catherine of York (14 August 1479 – 15 November 1527), married William Courtenay, 1st Earl of Devon
- Elizabeth Plantagenet (born circa 1464), married Thomas Lumley, Esquire, of Beautrove, Durham

Does anybody else with descent from the Plantagenets have a CHEK2 c.349 A>G genetic mutation?
ReplyDeleteMy husband and I both have it. We tried ancestry dna to see if we are cousins but they did not identify a kinship; they told us they can go back 12 generations. But no mutual cousins.
He had ancestors named Lancaster and I have ancestors named York including one who claimed descent from Geoffrey d’Anjou.
We were interested to read that Mary Plantagenet, illegitimate daughter of Edward IV, married a Harman, as my husband also has Harmans in his family tree.
Great list. Just to note that Elizabeth Plantagenet (born circa 1464) is now widely thought to have been called Margaret and she married Sir Thomas Lumley of Lumley Castle. They are my great grandparents.
