Show ContentsDelahunt History, Family Crest & Coats of Arms

In its ancient Gaelic form, the Irish name Delahunt was written Ó Dulchaointigh, which comes from the word dulchaointeach, which refers to a satirist. 1 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 Delahunt family

The surname Delahunt 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 Delahunt in counties Offaly (King's county) and Kilkenny. The ancient and important Delahunt sept sometimes claims descent from the O'Hara Buidhe, Chiefs of Leyney in County Sligo, through Lughaidh.

The Delahunt 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.
