Connolly - Irish Surname Origin & Meaning

Irish form: Ó Conghalaigh

Meaning: “valiant, brave”

Traditional stronghold: Galway, Monaghan

Pronunciation: KON-uh-lee; Irish O Conghaile: oh KUN-guh-luh

History of the Connolly name

The name is generally derived from elements suggesting 'valorous' or 'fierce', and O'Connolly septs are recorded in Monaghan, Connacht and elsewhere, none dominant enough to give the surname a single clear stronghold. It spread through Ulster and Connacht in particular. The name is most strongly associated in modern history with the labour leader executed for his part in the 1916 Rising, whose Edinburgh-born family had roots in Monaghan, an association that gave Connolly enduring resonance in Irish political memory well beyond its original clan geography.
