County Donegal Historical Heritage & Diaspora
County Donegal is the rugged northwestern crown of Ulster. Bounded by sea on three sides and cut off from the rest of the Republic of Ireland by partition, Donegal has maintained a fiercely independent Gaelic identity, boasting the largest Gaeltacht (Irish-speaking) population in the country.
Its sea cliffs at Slieve League are among the highest in Europe. In the nineteenth century, seasonal migration to Scotland shifted into massive permanent migration across the Atlantic, with the majority leaving from the nearby Port of Derry.
Donegal emigrants were uniquely drawn to hard-rock and coal mining in America. Thousands settled in Butte, Montana (“The Richest Hill on Earth”), where miners from Gweedore and the Rosses made up the core of the Butte Miners’ Union. In Scranton and the Pennsylvania Coal Valley, Donegal families established deep community fraternal halls.
Iconic Donegal surnames include Gallagher, Doherty, O’Donnell, Sweeney, Campbell, Bonner, and Boyle.
