Gilla

The name Gilla is derived from the Old Irish word 'gilla' or 'giolla', meaning 'servant' or 'devotee'. It was often used as a prefix in longer names, such as Gilla Críst (servant of Christ) or Gilla Pádraig (servant of Patrick), which later became anglicized as Gilchrist and Kilpatrick, respectively. Over time, 'Gilla' itself began to be used as a standalone given name.

While historically more common as a male element in names, the standalone form 'Gilla' has seen some usage as a female name, particularly in more modern contexts or as a diminutive. Its ancient roots connect it deeply to Irish and Scottish history and religious devotion.
