United States McCrosson migration to the United States +

A massive wave of Irish immigrants hit North America during the 19th century. Although many early Irish immigrants made a carefully planned decision to leave left Ireland for the promise of free land, by the 1840s immigrants were fleeing a famine stricken land in desperation. The condition of Ireland during the Great Potato Famine of the late 1840s can be attributed to a rapidly expanding population and English imperial policies. Those Irish families that arrived in North America were essential to its rapid social, industrial, and economic development. Passenger and immigration lists have revealed a number of early Irish immigrants bearing the name McCrosson:

The McCrosson 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: Indignante invidia florebit justus
Motto Translation: The just man will flourish in spite of envy.
