Who married Margaret Beaufort?

John de la Pole (27 settembre 1442 – tra il 1491 e il 1492) fu il secondo duca di Suffolk, secondo Marchese di Suffolk, quinto Conte di Suffolk.

Edmund Tudor, 1st Earl of Richmond (c. 1430 – 3 November 1456), also known as Edmund of Hadham, was the father of King Henry VII of England and a member of the Tudor family of Penmynydd. Born to Sir Owen Tudor and the dowager queen Catherine of Valois, Edmund was the half-brother of Henry VI of England. He was raised for several years by Katherine de la Pole, and Henry took an interest in Edmund's upbringing, granting him a title and lands once he came of age. Both Edmund and his brother, Jasper, were made advisers to the King, as they were his closest remaining blood relatives.

The brothers were made senior earls in the royal court and had influential positions in the Parliament of England. Edmund was also granted Baynard's Castle, London, and ran a successful estate. He was married to Lady Margaret Beaufort, after her first marriage was annulled. Prior to the start of the Wars of the Roses, Edmund liaised with Richard, Duke of York, and supported him when the King fell ill during 1453–1454. After war began in 1455, York sent Edmund to uphold the authority of the King in South Wales. While he was there, York was overthrown by the King and, in retaliation, Yorkist forces were sent to engage those of Tudor's in South Wales. Edmund was captured and imprisoned at Carmarthen Castle, where he died of the bubonic plague on 3 November 1456, three months before the birth of his son, the future Henry VII.

Sir Henry Stafford (c. 1425 – 4 October 1471) was the second son of Humphrey Stafford, 1st Duke of Buckingham and Lady Anne Neville, daughter of Ralph de Neville, 1st Earl of Westmorland, and Lady Joan Beaufort. Henry's elder brother, also named Humphrey, died before their father, and so it was Henry's nephew, also Henry, who became the 2nd Duke of Buckingham.

Stafford was the third husband of Margaret Beaufort, Countess of Richmond. The marriage was relatively long and successful and coincided roughly with the minority of Margaret's son, the future Henry VII of England. Both Sir Henry and Lady Margaret were descended from John of Gaunt and were supporters of Henry VI, the head of the House of Lancaster, in the early stages of the Wars of the Roses. However, Stafford later switched his allegiance to the House of York and towards the end of his life contributed to the restoration of Edward IV.
