Show ContentsMuldoon History, Family Crest & Coats of Arms

The surname Muldoon originally comes from the Gaelic as O Maolduin, a patronymic name meaning "descendent of Maolduin." The personal name Maolduin is composed of the elements "maol," meaning "chieftain," and "dún," meaning "fortress."

Early Origins of the Muldoon family

The surname Muldoon was first found in County Sligo (Irish: Sligeach), in the province of Connacht in Northwestern Ireland, where they had been anciently seated at Enniscrone and said to be directly descended from King Niall of the Nine Hostages, Ireland's General Commander/King who died in the fourth century. From his twelve sons many tribes are descended including O'Caomhain who controlled the tribes from the River Gleoir to the Easky, a tract of land which included the homes of about 30 tribes, including the Muldoons.

Some of the first records of the family appeared as a forename. Máel Dúin mac Áedo Bennán (died 661) was King of Iarmuman (West Munster.) A few years later, Máel Dúin mac Conaill (died 688) was a king in Dál Riata (now Western Scotland).

This resulted in the problem of one person's name being recorded under several different variations, creating the illusion of more than one person. Among the many spelling variations of the surname Muldoon that are preserved in archival documents are Muldoon, O'Muldoon, Meldon, O'Meldon, Maoldoon and many more.

United States Muldoon migration to the United States +

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world.

The Muldoon Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Pro fide et patria
Motto Translation: For faith and my country.
