Re: John Harcourt. I think this John Harcourt (Harecourte) husband of Ann Scales (Scalers) was a bastard. He was more than likely from Oxfordshire and definitely a grandson of Thomas Harecourte of of Stanton Harcourt Oxf., Ellenhall Staff.,and Market Bosworth, Leic. At the time of 1567-8 he was Lancastrian
A couple clues
Calendar of the Close Rolls Preserved in the Public Record Office 1953
Membrane 5.* 20 March 15. Westminster 1467
To the escheator in Cambridgeshire. Order to take an oath, of Maud late wife of John Deschalers, knight, and in presence of John More who has taken to wife Alice, one of the daughters of her late husband, and of John Harecourt who has married Anne, a second daughter, and of Margaret Deschalers the third daughter, to assign her dower. To the escheator in Hertfordshire. Like order.
To the escheator in Cambridgeshire. = John is from the Staunton Harcourt group. Probably son of Robert Harecourt Knight of the Garter before 1440 before his marriage to Margaret Byron. He could also be a son of Richard Harecourte.

There is also a John Harecourte de Wytney listed up until 1584. I do believe he was not the same person than John Harcourte esq. Usher to King's Henry VI and Richard III.
A very interesting link of a Noble bastard, John Harcourte basically given freedom to do as he pleases at 21.
