| Background: The name Dolan is fairly common to-day in Ulster - in the Catholic areas of Counties Cavan and Fermanagh - and in the Counties of Roscommon and Galway in Connacht. The latter is the place of origin of this sept which is a branch of the Ui Maine (Hy Many). In the census of 1659 the name appears principally in Counties Roscommon and Fermanagh (the portion dealing with Co. Galway is missing).
Variations: Dolan, Doolan, O'Dolan.
