I've been researching the history of Henry Fitz Roy, a previously little noticed illegitimate son of King John. Below I have posted what information I have collected on this individual. If anyone has anything else to add on this man, I'd appreciate knowing about it. Henry's one known wife, Eve de Whitchurch, was the mother by a prior marriage to Joan Champernoun, wife of Ralph de Willington. Joanappears to have been Eve's sole heiress. She appears in Complete Peerage under Wilington. I assume Henry Fitz Roy had a previous marriage, but, if so, I don't have those particulars. I've been unable to trace the subsequent history of Henry's lands or any descendants.
Interestingly, Eve de Whitchurch's 3rd husband was Giles de Clifford, who I believe is a member of the well known Clifford family.
