General Notes

The first of this ancient family of whom Dugdale takes notice was called Ponce, or Pons, who is represented as leaving three sons, Walter and Dru, considerable landed proprietors in the Conqueror's survey, and Richard FitzPonce, a personal of rank in the time of Richard I, and a liberal benefactor to the church.

K: Guillaume "Pons," Count d'Arcis and Toulouse.
Onslow: William, Count of Arques, who "acquired an unenviable reputation."
Butler: He was banished in 1053. Chart in Butler doesn't say why. Am
assuming he was not the William (or Nicholas), son of Judith, who
became a Monk. A Monk being less likely to be banished than a man with an
unenviable reputation.
Moriarty: Pons probably was the father of Richard Fitz Pons and of Walter
and Dru.
Lidd: William, Count of Arques.
Ashley: William of Talou, Count of Talou and Arques
