Gildea is an Irish surname of Gaelic origin that is believed to have first appeared in the early 17th century. The name derives from the patronymic Mac Giolla Dé, meaning “son of the servant of God”. This construction places the surname firmly within the Christian tradition that has shaped Irish culture for centuries.

The earliest recorded spelling appears in 1601 in the Records of Donegal where the name was written as Conor Mac Gillegea. Subsequent documents establish that the surname was also rendered as Kildea in some records. The name was associated with several localities, for example Ballykildea in County Clare and Ballykilladea in County Galway, both of which bear the clan’s toponymic legacy.

In the 17th century, the Gildea clan was primarily a Donegal sept. Many families moved into neighbouring counties such as Mayo, where they remained a prominent presence. A notable figure in the early 17th century was Daniel Guilday, who served as vicar‑general of the Diocese of Killaloe, Co. Clare in 1624. The surname also appears in English church registers, with examples including the marriage of William Gildea and Mary Boyle at St. James, Paddington, London in 1840, and the christenings of Mary Kildea in Manchester Cathedral (1845) and Elizabeth Gildea in Liverpool (1857).

During the 19th century, the great Catholic Emigration wave brought many Gildeas abroad. In particular, the potato famine prompted the exodus of people bearing the name to the United States, Britain, Canada, and Australia. The name remains common in the counties of Donegal, Sligo and Mayo, the three states in north–west Ireland where it is still found in the highest concentrations.

Among the contemporary bearers of the surname is the late James Gildea (1838–1920), who was born in County Mayo and co‑founded the St. John’s Ambulance Association. His dedication to medical aid reflects the normative Christian devotion that is encoded in the surname’s meaning.

The surname Gildea has several accepted orthographic variants, including Gilday, Gildey, Gildy, Gillea, Gilleo, Gilley and Gilleye. These alternative spellings appear in historical records, reflecting the anglicisation of the original Gaelic forms over time.
