Origin of the Name Deegan
The origin of the name
Deegan was found in the allfamilycrests.com archives. Variants of Deegan include Duigan and Deighan. This sept originated in the barony of Clandonagh, County Leix.
A sept or clan is a collective term describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory. Irish septs and clans that are related often belong to even larger groups, sometimes called tribes.
In Irish this name is O'Duibhginn and all the previously mentioned variants are the anglicized forms of this. They were the keepers of the Bell of Saint Molua and their lands amounted to 2000 acres, being granted to the notorious Sir Charles Coote, Earl of Mountrath, in the year 1667. From County Leix the name spread to Clare, Galway and Wexford and a very famous person of the family was James Robertson Duigan, 1882-1951, the pioneer Australian Airman whose flight in a plane built by him in 1910 is commemorated by a monument at Lancefield, Victoria. He was originally from County Kilkenny.
The Deegan coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all Deegan descendants.
