Migration of the O'Cassidey family to the New World and Oceana
became inhospitable for many native Irish families
in the 19th centuries. Poverty, lack of opportunities, high rents, and discrimination forced thousands to leave the island for North America. The largest exodus of Irish settlers occurred with the Great Potato Famine
of the late 1840s. For these immigrants the journey to British North America and the United States was long and dangerous and many did not live to see the shores of those new lands. Those who did make it were essential to the development of what would become two of the wealthiest and most powerful nations of the world. These Irish immigrants were not only important for peopling the new settlements and cities, they also provided the manpower needed for the many industrial and agricultural projects so essential to these growing nations. Immigration and passenger lists have documented the arrival of various people bearing the name O'Cassidey to North America: 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'Cassidey 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.
