Migration of the O'Cassidy family to the New World and Oceana
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. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. 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'Cassidy name: Patrick Cassidy who settled in Rhode Island, and later moved to Norwich in Connecticut, where he became one of America's first surgeons. Edward, Hugh, James, John, Patrick, Thomas and William Cassady who all arrived in Philadelphia between 1840 and 1865.
The O'Cassidy 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: Frangas non flectes
Motto Translation: Thou may'st break, but shalt not bend me.
