Migration of the O'Kirwant family

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination.

These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the O'Kirwant name: William Kirvan, who arrived in Philadelphia in 1853; Elizabeth, Maria, Michael, and Thomas Kirwan, all arrived in Philadelphia between 1820 and 1844; John Kirwin settled in Philadelphia in 1851..



The O'Kirwant 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: Mon Dieu, mon Roi, et ma patrie
Motto Translation: Mon Dieu, mon Roi, et ma patrie.
