Baldwin, Milligan, Molohan, Mullahan, Ó Maolagáin


Mulligan came from the Gaelic name Ó Maolagáin, derived from the word “maol” which means ‘bald’. The sept was located in Co. Donegal, in the baronies of Boylagh and Raphoe, where they were rulers of the territory of Tír MacCartháin. They were dispossessed in the seventeenth century, and hence the name became widespread throughout the country, now being found in similar numbers in each of the four provinces.
