He was a crusader with his Lollard brother (and possible lover)[2] John Clanvowe, with whom he was buried inside the Arap Mosque in Istanbul.
Sir William Neville was a knight of the chamber to King Richard II of England and was named constable of Nottingham castle.
The two shared a special bond, despite the fact Sir William had a wife, firstly Elizabeth Le Waleys and secondly Alice de St. Philbert.
Clanvowe, a poet, wrote a ballad in honor of a visit of King Richard II to Nottingham castle, "The Jest of Robin Hood".
[4] In an entry for 1391 in the chronicle compiled in the XIV century by the monks of Westminster Abbey, it is written that William Neville died of grief for the death of John Clanvowe: "It was also on October 17, that in a village near Constantinople in Greece the life of Sir John Clanvowe, a distinguished knight, came to its close, causing to his companion on the march, Sir William Neville, for whom his love was no less than for himself, such inconsolable sorrow that he never took food again and two days afterward breathed his last, greatly mourned, in the same village.
