Origin of the Name Molihan
The ancient history of the name
Molihan was found in the allfamilycrests.com archives. The variants of Molihan include Molohan, Mulligan, Milligan and Mulqueen. The Sept from which this name is derived is the O'Mothlachain Sept, which is also anglicized as Molan. The O'Maolachain Sept of County Longford also used Molihan as the anglicized form of their native Gaelic name, as well as Mallaghan. Some of the name are from the O'Maolagain Sept, often rendered as Mulligan. This Sept is of distinguished origin, its Chiefs being lords of a territory called Tir McCarthain, in the baronies of Boylagh and Raphoe, County Donegal. They were dispossessed in the Ulster Plantation of the early seventeenth century. Today the bearers of this name are chiefly located in Counties Mayo and Monaghan. In 1659 they were found in considerable numbers in Monaghan and in Fermanagh, and also in the Longford area. In County Clare the name Molihan is sometimes changed to Mollahan.
The Molihan coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all Molihan descendants.
