Delahunty History, Family Crest & Coats of Arms

In its ancient Gaelic form, the Irish name Delahunty was written O Dulchaointigh, which comes from the word dulchaointeach, which refers to a satirist. The ancestor of this Irish family is said to have been Muintir Cormac or Muintir Dulchonta, which was gradually anglicized over the years, until it was rendered as Delahunt or Delahunty. Although the name appears quite French, it seems highly unlikely that there are any French origins to the name, other than the Norman influence of the clerks, who began processing Irish names, as early as the 12th century.

Early Origins of the Delahunty family

The surname Delahunty was first found in Ormond, where records of the name can be found in deeds from around 1441 on. Petty's "census" of 1659 showed bearers of Delahunty in counties Offaly (King's county) and Kilkenny. The ancient and important Delahunty sept sometimes claims descent from the O'Hara Buidhe, Chiefs of Leyney in County Sligo, through Lughaidh.

United States Delahunty migration to the United States +

Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name Delahunty or one of its variants:

The Delahunty 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: In fide et in bello fortes
Motto Translation: Firm in faith and war.
