[2] Genealogist Douglas Richardson also mentions the alleged affair between Alice and the Cardinal.
According to Richardson, 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, born say 1390.
"[3] Furthermore, 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.
