Early Origins of the Crossant family

There they were an off-shoot of the notable Clan O'Moore which was the leading sept of the 'Seven Clans of Leix'.

Migration of the Crossant family

The English-ruled Ireland of the late 18th and 19th centuries featured a rapidly increasing population and an agricultural-based economy. This combination proved to be disastrous in the 1840s after a couple of failed potato harvests. Thousands died of disease and starvation, and thousands more left the country, often bound for North America. Those that survived the journey to North America were put to work building the bridges, canals, roadways, and railways needed for the development of an industrial society. Those Irish, although often despised by those already established in North American cities and towns, played an instrumental role in making Canada and the United States the powerful and wealthy nations that they are today. An examination of early immigration and passenger lists has shown many immigrants bearing the name Crossant: Thomas and his wife Jane, and children John, Agnes, Jane, Helen, and Thomas all settled in Charles Town, S.Carolina in 1767; Neal Crossan settled in Pennsylvania in 1772.



The Crossant 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.
