Connally, O’ Connally, O’ Connolly, Ó Conghaile


The Connolly name originated in the province of Connacht in the west, and also in Co. Monaghan in the north, but has since been widely dispersed throughout the country. The name comes from the Gaelic “conghaile”, which means ‘valorous’. Today, Connolly is the 23rd most numerous name in Ireland, being most common in the province of Ulster.
