Muldoon Family Crest
The Irish surname Muldoon is an anglicized form of the Gaelic name Ó Maoldúin meaning “descendant of Maoldúin,” a personal name composed of the elements maol meaning “chieftain” and dún meaning “fortress.” This name is chiefly associated with counties Sligo and Fermanagh and the southern province of Munster. Historically it is said that the Muldoon’s were of royal birth, being styled as the kings of Lurg in the book known as “The annals of Loch Ce.” However in about the year 1400 the clan was defeated in battle by the MacGuires, and whilst they continued to be of importance in Fermanagh, elsewhere in the country their power bases gradually faded away. The name is first recorded in the New World in 1803 when James Muldoon arrived in New York. Today there are approximately 4,000 bearers of the name Muldoon living in the US.
