First name of William and surname of de Colleville from Cynthia Glover (nee Coleman), whose great-great-grandfather was William Samuel Allen b.1843. (William's sister, Martha Allen, married Charles Oliver, youngest son of James and Ruth Oliver).

Michael Stanhope in his 2007 "The History of the Stanhope Family" writes, “William Crispin II was an Anglo-Norman lord who held land in Wetherby, Wheldrake, Coxwold, and Goodmanham in Yorkshire, and in Ancroft in Northumberland, as mesne-tenant of William de Percy. Goodmanham [Godmundin] is a small village situated 2 miles to the north-east of Market Weighton. It was the main pagan site of worship in the north of England, housing the Temple of Delgovine - the place of God's image - dedicated to Odin. William Crispin 11. also held land, principally, in Normandy: 'William Crispin the younger gave the tithe of the mill and of his desmene which he had in Le Mesnil-Hubert, the church and tithe of Druicort, what Robert Malcovernant held of him, one house in Livarot with all its customs, half of the church and tithe of Bournainville'.

Michael writes that William Crispin II and Agnes de Mauvoison had six sons:
1. Philip de Colleville
2. William Crispin III
3. Amaury Crispin, 1090-1168, Seigneur de Champtoceaux
4. Simon Crispin, 1095-1145
5. Manasser Crispin, 1097-1160
6. Thomas de Colleville, b. 1130

Thomas, the youngest son of this Anglo-Norman family, obtained, by gift of his father,Yearsley, also spelt Everley, Ifferley, and Yresley, a name deriving from Efor's Leigh, meaning field of the wild boar, near York, where he granted lands to Byland Abbey: 'In the reign of Stephen, Thomas de Colvyle gave pasture in the wood of Eversley [Yearsley] to Byland Abbey.'
