He was born in Abergavenny, Monmouthshire, Wales, the son of George Nevill, 4th Baron Bergavenny and Margaret Fenne. He was an elder brother of Sir Edward Nevill who was executed in 1540 charged with "devising to maintain, promote, and advance one Reginald Pole, late Dean of Exeter, enemy of the King, beyond the sea, and to deprive the King". (Reginald Pole was a Catholic exile and seems to have been a cousin of Nevill's). They had two sisters, Jane and Elizabeth.

The mother of George and Edward Neville was Margaret Fenne, who was born in about 1444 at Sculton Burdeleys in Norfolk, England. She was the second of the three wives of the 4th Baron Bergavenny, and is recorded as having died on September 28, 1485.
