Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Mulrien originally appeared in Gaelic as Ó Maoilriain, formerly Mulryan, but now abbreviated to Ó Riain. 1

Early Origins of the O'Mulrien family

The surname O'Mulrien was first found in County Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster. 1

According to O'Hart, the family claim descent from the Heremon Kings of Ireland through the MacMorough pedigree, specifically Cormac, brother of Eoghan who was ancestor of O'Righin; anglicized Mulrain, O'Ryan, Ryan and Ryne. 2

However, MacLysaght claims the family claim descent from O Maoilriain located in Owney, formerly called Owney O'Mulryan which forms two modern baronies on the borders of Limerick and Tipperary. 3 As both authorities were Chief Heralds of Ireland in their own time, we must leave the reader to ponder which of the two is more likely.

Migration of the O'Mulrien family

Irish families left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence. The earliest wave of Irish migration, however, occurred during the Great Potato Famine of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the O'Mulrien name: Alexander, Alfred, Catherine, Cornelius, Daniel, Denis, Edward, Jeremiah, John, Margaret, Mathew, Michael, Patrick, Peter, Richard, Thomas, Timothy and William Ryan all arrived in Philadelphia between 1840 and 1860.



The O'Mulrien 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: Malo mori quam fodari
Motto Translation: I would rather die than be disgraced.
