Margaret married John Beaufort, 1st Earl of Somerset, son of John of Gaunt, 1st Duke of Lancaster and his mistress Katherine Swynford. They had six children:[1]

In 1399, she was invested as a Lady Companion, Order of the Garter (L.G.).[2] After Beaufort died in 1410 (in the Tower of London), she married his nephew Thomas of Lancaster, 1st Duke of Clarence, the son of King Henry IV. They had no children.[2] She died on 31 December 1439 at St. Saviour's Abbey, Bermondsey, in London, England.[2] Margaret and both her husbands are buried together in a carved alabaster tomb in Canterbury Cathedral that shows her lying between the two of them.


Through her son, the 1st Duke of Somerset, Lady Margaret is an ancestress to the Tudor monarchs. Both Lady Joan, Queen consort of Scotland, and the Duke of Somerset, are ancestors of King George I of Great Britain. As such, both children are ancestors to the current British royal family.[3]

Lady Margaret's sister, Alianore Holland, the Countess of March is also a direct ancestor of George Washington, 1st President of the United States of America.
