There are several distinct sources of the McMorre surname in Ireland. Most of the name find their roots with the Anglo-Norman "Strongbow" invasion of the 12th century. Many of these became de Mora. Others derived from the Old Irish "O Mordha," from the word "mordha," meaning "stately," or "noble." 1 The English surname McMorre is derived from the personal name "More," which is itself derived from the Old French word "maur," meaning "Moor."

Migration of the McMorre family

Ireland went through one of the most devastating periods in its history with the arrival of the Great Potato Famine of the 1840s. Many also lost their lives from typhus, fever and dysentery. And poverty was the general rule as tenant farmers were often evicted because they could not pay the high rents. Emigration to North America gave hundreds of families a chance at a life where work, freedom, and land ownership were all possible. For those who made the long journey, it meant hope and survival. The Irish emigration to British North America and the United States opened up the gates of industry, commerce, education and the arts. Early immigration and passenger lists have shown many Irish people bearing the name McMorre: Miles Moor, who settled in South Carolina in 1716; James Mooers, and his wife Isabel, who came to New Hampshire in 1725; Aaron Moore, who immigrated to Virginia in 1744.



The McMorre 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: Conlan-a-bu
Motto Translation: Conlan forever.
