Cummins — Keepers of the Church

Cummins anglicises two distinct Gaelic names: Ó Cuimín in Connacht, where the family served as erenaghs — lay administrators — of a church tradition founded by St. Cuimín Fada, with the parish of Kilcummin near Killala still carrying the name; and, separately, Ó Comáin in Munster, an unrelated sept with its own line.

Two septs, two provinces, one shared name — church stewardship in the west, a separate family history in the south.

Irish form: Ó Cuimín
