House of Tudor [ edit ] Main articles: House of Tudor and Tudor period The Tudors descended in the female line from John Beaufort, one of the illegitimate children of John of Gaunt (third surviving son of Edward III), by Gaunt's long-term mistress Katherine Swynford. Those descended from English monarchs only through an illegitimate child would normally have no claim on the throne, but the situation was complicated when Gaunt and Swynford eventually married in 1396 (25 years after John Beaufort's birth). In view of the marriage, the church retroactively declared the Beauforts legitimate via a papal bull the same year.[87] Parliament did the same in an Act in 1397.[88] A subsequent proclamation by John of Gaunt's legitimate son, King Henry IV, also recognised the Beauforts' legitimacy, but declared them ineligible ever to inherit the throne.[89] Nevertheless, the Beauforts remained closely allied with Gaunt's other descendants, the Royal House of Lancaster. John Beaufort's granddaughter Lady Margaret Beaufort was married to Edmund Tudor. Tudor was the son of Welsh courtier Owain Tudur (anglicised to Owen Tudor) and Catherine of Valois, the widow of the Lancastrian King Henry V. Edmund Tudor and his siblings were either illegitimate, or the product of a secret marriage, and owed their fortunes to the goodwill of their legitimate half-brother King Henry VI. When the House of Lancaster fell from power, the Tudors followed. By the late 15th century, the Tudors were the last hope for the Lancaster supporters. Edmund Tudor's son became king as Henry VII after defeating Richard III at the Battle of Bosworth Field in 1485, winning the Wars of the Roses. King Henry married Elizabeth of York, daughter of Edward IV, thereby uniting the Lancastrian and York lineages. (See family tree.)

Arthur II was succeeded by his cousin; whose mother was of the English Royal House of Tudor and whose father was of the Nassau House of Orange-Tudor. Anne I herself would identify as of the Royal House of Tudor throughout her reign, all but forsaking her father’s House.
