Connelly

Connelly is a variant spelling of Connolly, representing two distinct Gaelic families — one from Connacht (Ó Conghaile) and one from Ulster (Ó Coingheallach). The name is found across all four provinces.

Origins and History

Connelly — the variant spelling of Connolly — represents two historically distinct Irish families. The primary Connacht family, Ó Conghaile, held territory in south Galway and were part of the tribal grouping of Connacht west of the Shannon. The personal name Conghal means fierce as a hound — con (hound) combined with gal (fierceness, valour), giving the family a martial name typical of the early Irish aristocracy.

The Ulster family — Ó Coingheallach — held territory in County Monaghan and derived their name from a different personal name, coingheallach, meaning faithful to pledges or trustworthy. This etymological distinction maps to the geographic one: Connellys in Connacht and Munster typically derive from Ó Conghaile, while those in Ulster more often trace to Ó Coingheallach.

Clare and south Galway

The Ó Conghaile of Connacht were concentrated in the barony of Loughrea in east Galway and in north Clare. Their territory bordered that of the O'Brien kings of Thomond, and they appear in medieval records as subject lords in the political orbit of both the O'Briens and the O'Conors of Connacht. In Griffith's Valuation (1847–1864), Connelly and Connolly together are found most densely in Galway, Clare, and Monaghan.

James Connolly

James Connolly (1868–1916) — trade union leader, socialist, and leader of the Irish Citizen Army in the 1916 Rising — bore the Connolly form of the name. Born in Edinburgh to Irish emigrant parents, he was executed by firing squad for his part in the Rising. He remains one of the central figures in Irish republican and labour history.

In the Diaspora

In the United States, Connelly is found across all major Irish-American communities. Marc Connelly, the American playwright who won the Pulitzer Prize for The Green Pastures (1930), is a notable bearer. The name is particularly well represented in New York, Boston, and Chicago.

Jennifer Connelly — the American actress — is of Irish descent. In Australia and Canada, Connelly appears in records from the mid-19th century following the Connacht and Ulster emigration routes.
