United States Cassedy migration to the United States +

Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name Cassedy:

West Indies Cassedy migration to West Indies +

The British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association. 4

The Cassedy 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.
