There are several distinct sources of the Mohr 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 Mohr is derived from the personal name "More," which is itself derived from the Old French word "maur," meaning "Moor."

United States Mohr migration to the United States +

In the mid-19th century, Ireland experienced one of the worst periods in its entire history. During this decade in order to ease the pressure of the soil, which was actually depleted by the effects of the previous years' grain crops, landowners forced tenant farmers and peasants onto tiny plots of land that barely provided the basic sustenance a family required. Conditions were worsened, though, by the population of the country, which was growing fast to roughly eight million. So when the Great Potato Famine of the mid-1840s hit, starvation and diseases decimated the population. Thousands of Irish families left the country for British North America and the United States. The new immigrants were often accommodated either in the opening western frontiers or as cheap unskilled labor in the established centers. In early passenger and immigration lists there are many immigrants bearing the name Mohr:

The Mohr 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.
