John Neville was the only son of John Neville, 3rd Baron Neville of Raby, by Elizabeth Latimer, suo jure Baroness Latimer of the older barony created by writ in 1299. He proved his age in 1404 and was styled Lord Latimer during his lifetime. He secured a divorce from Maud Clifford and died without legitimate issue. His lands were devised or settled through the Neville family, eventually passing to George Neville, who was summoned to Parliament as Baron Latimer in 1432. The later 1432 dignity was treated as a new barony rather than a continuation of John’s older Latimer barony.
