Gille / Giolla

The name Gille is derived from the Old Irish word 'gilla' or 'giolla', meaning 'servant' or 'lad'. It was often used as a prefix in compound names, particularly in Scotland and Ireland, to denote a devotee or servant of a particular saint. For example, Gille Easpuig (servant of the bishop) became Gillespie, and Gille Chriosd (servant of Christ) became Gilchrist.

Over time, Gille also emerged as a standalone given name. Its usage reflects the strong religious and clan affiliations prevalent in Gaelic-speaking cultures. While less common as a primary given name today, its influence is still seen in numerous surnames and place names across Scotland and Ireland.
