谁嫁给了Edmund Tudor, 1st Earl of Richmond？

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.

玛格丽特·博福特女领主（/ˈboʊfərt/, BOH-fərt; 或 /ˈbjuːfərt/, BEW-fərt)，1443年5月31日—1509年6月29日），后为里奇蒙和德比伯爵夫人（Countess of Richmond and Derby），是15世纪末玫瑰战争的重要人物，都铎王朝开国之君亨利七世的母亲。

作为爱德华三世的后裔，她把有争议的英格兰王位继承权传给了儿子亨利·都铎。她利用这一时期的政治动荡，积极地为儿子争取王位。她的努力最终使亨利在博斯沃思平原战役对理查三世取得了决定性的胜利，因此她在策划都铎王朝登基的过程中发挥了重要作用。其中有两位英格兰最著名的君主：亨利八世（她的孙子）和伊丽莎白一世。她的儿子加冕为英王亨利七世。她拥有相当大的政治影响力和个人自主权——这两点对于她那个时代的女性都被认为是不寻常的。在她儿子统治时期，她也是一个主要的赞助人和文化赞助人，开创了都铎王朝的广泛赞助人时代。

她因于1505年创立剑桥大学基督学院和开始创立剑桥大学圣约翰学院并最终在她身后于1511年由其遗嘱执行人完成而为人铭记。牛津大学玛格丽特女领主大厅，19世纪的一座以她命名的基金会是第一所招收女子的学院，以她命名，且在学院教堂有她的雕像。
