United States Mower migration to the United States +

The Irish emigration during the late 18th and 19th century contributed to the melting pot of nationalities in North America, and the building of a whole new era of industry and commerce in what was seen as a rich, new land. Ireland'sGreat Potato Famine resulted in the worst economic and social conditions in the island's history. And in response to the hunger, disease, and poverty, during this decade the total number of emigrants to leave for North America rivaled all the previous years combined. Those from this decade that arrived on North American shores were not warmly welcomed by the established population, but they were vital to the rapid development of the industry, agriculture, and infrastructure of the infant nations of the United States and what would become Canada.

The Mower 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.
