The Irish name O'Mulloy was originally written in a Gaelic form as Ó Maolmhuaidh, which is derived from the word "muadh," which has the dual meaning of "noble" and "big and soft." 1

Early Origins of the O'Mulloy family

The surname O'Mulloy was first found in County Offaly (Irish: Uíbh Fháilí) originally the Kingdom of Uí Failghe, located in central Ireland in the Province of Leinster, where they held a family seat from ancient times.

Albin O'Molloy or Alpin O'Moelmhuaidh (d. 1223), was Bishop of Ferns, a native Irishman, "who became a Cistercian monk at Baltinglass, and eventually rose to be abbot of that house. In Lent 1186, when John, archbishop of Dublin, held a synod at Holy Trinity Church, Albin preached a long sermon on clerical continency, in which he laid all the blame for existing evils on the Welsh and English clergy who had come over to Ireland. On 5 Nov. he was appointed by Pope Innocent III, with the Archbishop of Tuam and Bishop of Kilmacduagh, to excommunicate the Bishop of Waterford, who had robbed the Bishop of Lismore." 2

Migration of the O'Mulloy 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'Mulloy name: Charles Molloy, who came to Boston in 1725; Arthur Molloy, who settled in Nova Scotia in 1750; William Mulloy, a Loyalist, who came to Ontario, Canada from America in 1796.



The O'Mulloy 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 foedari
Motto Translation: I would rather die than be disgraced.
