History of the Mulligan name

Mulligan is Ó Maolagáin, a diminutive of maol, the tonsured one, suggesting an ancestor in religious service. The sept were chiefs of a territory in the barony of Raphoe, County Donegal, until the upheavals of the seventeenth century scattered them into Mayo and Monaghan. Some families anglicised the name as Molyneux, and a few even translated the 'bald' element as Baldwin. Literature gave the name two immortals: stately, plump Buck Mulligan of Joyce's Ulysses, and in history the Coleraine-born tailor Hercules Mulligan, whose New York spying for Washington was celebrated anew in the musical Hamilton.
