Show ContentsMuldon History, Family Crest & Coats of Arms

The surname Muldon originally comes from the Gaelic as Ó 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 Muldon family

The surname Muldon 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).

United States Muldon migration to the United States +

A massive amount of Ireland's native population left the island in the 19th century for North America and Australia in hopes of finding more opportunities and an escape from discrimination and oppression. A great portion of these migrants arrived on the eastern shores of the North American continent. Although they were generally poor and destitute, and, therefore, again discriminated against, these Irish people were heartily welcomed for the hard labor involved in the construction of railroads, canals, roadways, and buildings. Many others were put to work in the newly established factories or agricultural projects that were so essential to the development of what would become two of the wealthiest nations in the world. The Great Potato Famine during the late 1840s initiated the largest wave of Iris immigration. Early North American immigration and passenger lists have revealed a number of people bearing the name Muldon or a variant listed above:

The Muldon 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.
