Notes for: Alice FITZALAN
Following her marriage she became the mistress of Cardinal Henry Beaufort, and bore him an illegitimate daughter, Jane Beaufort
There is no contemporary evidence that Alice was either the mistress of Henry Beaufort, or that she was the mother of his illegitimate daughter Joan Beaufort.
The earliest appearance of the claim that Alice was the girl's mother is in "The Winning of the Lordship of Glamorgan", written by a later Sir Edward Stradling, a descendant, between 1561 and 1566. Beaufort did indeed father an illegitimate daughter, Joan Beaufort, possibly before Henry took holy orders on 7 April 1397.
