The descendants of Cormac Gaileng, great grandson of Olioll Olum were called Gailenga, the race of Gaileng, and they gave their name to the barony of Gallen in Mayo.[2]

Viscount Dillon of Costello-Gallen, created in 1622 for Theobald Dillon, Lord President of Connaught, held the title in the Peerage of Ireland.
