HUGH DE SAINT PHILIBERT, son and heir, did homage for his father's lands in Berks in 1240, In 1241-42 he fined for not crossing with the King into Gascony; in 1242-43 he held Cresswell in demesne, and 1/2 fee in Heythrop, Oxon. He died in or before June 1249. [Complete Peerage XI:365, (transcribed by Dave Utzinger)]

A word about the name "St. Philbert". I find numerous references to the name "St. Philibert" and "St. Philbert". As far as I can determine they are two different spellings for the same family. I find the same people spelled with either spelling. Even the original saint (died 684) that the family is presumed to be named after, I find spelled both ways.
