John. I don't think you have read any of the sources I presented nor have you given any new evidence to prove your claims.
1. John Harcourt (1451-1485), the eldest son Robert, eldest son of Thomas Harcourt, married Anne Norreys.- New - Yes this is correct and as stated before, he died June 26th 1485
2. John Harcourt (c. 1420- aft. 1495), Sheriff of Staffordshire, uncle of John (#1 above), apparently married (1) Eleanor Lewknor; married (2) Margaret Brace. - New - There is no proof or documentation of a marriage to Eleanor Lewknor, the rest is correct. "It appears that a marriage to Eleanor Lewknor was invented to explain how John (not Thomas) Harcourt of Ranton, Staffordshire, came into possession of that manor, since Ranton in 1450 was owned by the Lewknors. However, no marriage is needed to explain the situation. Sir Roger Lewknor (son of Sir Thomas) conveyed the reversion of the manor of Ranton held by Edward Doyly to John Harcourt for payment of 500 marks in 1473. Thus, we see that John Harcourt purchased Ranton. We have found no evidence of a marriage between a Harcourt and an Eleanor Lewknor, and believe she should be removed from the Harcourt pedigree." TAG Jan/April 2004 pgs. 98-9. This John Harcourt was still alive in 1495.
3. John Harcourt, presumed eldest son of John (#2 above), married Anne Scalers/Deschallers and died well before 1493, when his widow's IPM shows that after his death she married Giles Wellesbourne, and that her daughter Margery was betrothed to Humphrey Wellesbourne. - New - Not the son of #2, no documentation exists to tie another John Harcourt son of John Harcourt or to Staffordshire. The rest is True
4. John Harcourt, bastard, of Wytney, Oxfordshire, alive in 1493 when his "daughter and heir" Margaret was abducted. There is no reason to suppose that he had a wife named Anne (you confused him with #1 above), and he was clearly not John Harcourt #3, who was already dead and buried. - New - As stated now for the third time he died bef Jan 11 1485, had a Wife Anne and a daughter Margaret. See the evidence below.

I would be fine if you proved me wrong with actual sources but you don't have any to give. All the sources I have used are in my original post. https://groups.google.com/forum/#!searchin/soc.genealogy.medieval/harecourt$20tag%7Csort:date/soc.genealogy.medieval/aWHunzol9PQ/0FG8Hsf7CwAJ
