MacMawen History, Family Crest & Coats of Arms
In its ancient Gaelic form, the Irish name MacMawen was written Mac Mathghamhna, which later became Mac Mathuna. Both names are derived from the word "mathghamhan," which means "bear."
Early Origins of the MacMawen family
The surname MacMawen 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. 
"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."

Migration of the MacMawen family
Many Irish families boarded ships bound for North America in the middle of 19th century to escape the conditions of poverty and racial discrimination at that time. Although these immigrants often arrived in a destitute state, they went on to make important contributions to the emerging nations of the United States and Canada. An inquiry into many immigration and passenger lists has revealed many early immigrants to North America bearing the MacMawen family name: Bernard, Francis, James, John, Michael, Patrick MacMahan, who all arrived in Philadelphia, Pennsylvania between 1840 and 1860; Mary McMahan settled in Boston Massachusetts in 1849.
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.
