Sir Walter l'Enfant the younger (died c. 1317), lord of Carnalway, County Kildare was an Irish judge and landowner.
Through the first Sir Walter's marriage to Joan, the l'Enfant family acquired the lordship of Carnalway.
[1] He was a close associate of John FitzGerald, 1st Earl of Kildare: he accompanied him to the Netherlands, and was a witness to the truce of 1295 which ended Kildare's lengthy feud with Richard Óg de Burgh, 2nd Earl of Ulster.
He married Elizabeth, by whom he had issue, including the third Walter l'Enfant, who saw military service in the 1330s.
[4] After her first husband's death Elizabeth remarried William de Wellesley, an ancestor of the Duke of Wellington.
