In its ancient Gaelic form, the Irish name Mahan was written Mac Mathghamhna, which later became Mac Mathuna. Both names are derived from the word "mathghamhan," which means "bear."

Early Origins of the Mahan family

The surname Mahan was first found in County Clare (Irish: An Clár) located on the west coast of Ireland in the province of Munster, where the MacMahons were lords of Corca Baisgin; and possessed the greater part of the baronies of Moyarta and Clonderlaw. [1]

"The Munster MacMahons formerly possessed the greater part of the Baronies of Moyarta and Clonderalaw, in the County Clare, in which county the predominant name now is McMahon." [2]

United States Mahan migration to the United States +

Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name Mahan or one of its variants:

The Mahan 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: Sic nos sic sacra tuemur
Motto Translation: Thus we guard our sacred rights.
