Giles surname meaning

Giles is primarily an English surname of Norman origin from the medieval personal name Giles (Middle English Giles, Old French Gil(l)e(s)), from Latin Aegidius—often linked to Greek aigidion, “young goat.” The name spread with the cult of Saint Gilles of Provence. Gyles, Gilles, and Jiles are related spellings. In Ireland, Giles was sometimes adopted for Gaelic Ó Glaisne (from glas, “green/blue/gray”). Parent’s name is high confidence for the Norman personal-name route that dominates English and American use, with the Irish substitution noted as a secondary path.
