John Neville (died 1420)

John acquired a castle at Kirkbymoorside, about 13 miles north of his father's caput of Sheriff Hutton.

[6] However, sometime before 1396, his father had married Joan Beaufort, a legitimated daughter of John of Gaunt, and soon after, and possibly as a direct consequence, the earl commenced a long string of enfeoffments in favour of the children he was now having with Joan, particularly the eldest son, Richard, later Earl of Salisbury.

This effectively disinherited John who, curiously, seems to have "acquiesced" in the process as, on one occasion at least, he acted as a witness to one of the transfers.

This will was superseded by a much later one, written after John had predeceased his father,[1] which happened whilst he was in France, shortly before 20 May 1420 (probably at Verneuil).

This created lasting divisions within the Neville family, resulting in the Neville–Neville feud, which later subsumed into the Wars of the Roses.
