The Irish surname Dolan is an anglicized form of the Gaelic names Ó Dubhshláin, or Ó Dubhlainn. The name is chiefly found in Tyrone and its adjacent counties. A second main sept belonged to County Sligo, and their territory lay in the barony of Corran. In 1316, one Gillananaev O'Devlin, of the county, standard bearer to the O' Connors, was slain in battle. The name is still prominent in Counties Sligo, Leitrim and Cavan, but has, in some areas, been widely changed to Dolan. The name has been found in the United States since the 18th Century when a Peter Dolan arrived in Philadelphia in 1745, and today there are approximately 28,000 bearers of the name Dolan living in the United States.
