The pedigree is from John Nichols, "The History and Antiquities of the County of Leicester", 1807, Vol. III, Part 1, p. 174. I do not have access to the pedigree.

Greg, if you're still around and don't yet have an answer to your question, a 2008 post (with sources) by John Watson answers your question about Alexander Percy. See here:

Extract:

"Sir Alexander de Percy, of Ormesby and Sneaton, the son and heir of
William de Percy of Kildale and Joan Neville. He was said to be 14
years old in July 1295 at the inquisition post mortem of his father
[10].

By his wife Juliana he was the father of Alexander, William, John,
Margaret and Eleanor.

Margaret de Percy married Sir John Mowbray of Kirklington, ancestor of
Ingleby and Gascoigne

Eleanor de Percy married Sir John Clervaux of Croft."
