History of the Muldoon name

Muldoon is Ó Maoldúin, usually interpreted as 'chief' or 'warrior of the fort', from maol and dún. The principal sept held the territory of Lurg in north Fermanagh, where they were lords before the rise of the Maguires, and Fermanagh with adjacent Tyrone and Monaghan remains the name's homeland. Lesser septs of the same name existed in Clare and Sligo. The surname has travelled well: it belongs to a Pulitzer-winning poet from Armagh, a Prime Minister of New Zealand, and a long line of Ulster musicians and sportspeople.
