In 1269 Alice granted the manor of Kingston to her younger son Gerard I de Lisle, whose family adopted the arms of FitzGerold: Gules, a lion statant guardant argent crowned or.
[2] He resided chiefly at Stowe Nine Churches in Northamptonshire and Kingston Lisle (in Sparsholt), Berkshire (now Oxfordshire).
In 1329 he proved his right to free warren in his demesne lands at Stowe and Kislingbury, Northamptonshire by grant of King Henry III to Geoffrey de Armenters.
In 1332 Richard Herman was attached to answer Gerard de Lisle concerning a plea why with force and arms he broke the close of the said Gerard at Alverston, Hampshire and dug in his separate soil there, and took and carried away twenty cartloads of earth extracted therefrom to the value of 40 shillings, and depastured, trampled on, and consumed his grass once growing there to the value of 60 shillings.
He married twice: In 1351 Philip Warde, formerly bailiff of Gerard de Lisle in the manor of Walberton, Sussex, owed him a debt of £10 7s.
