Origin of the Name Halligan
The ancient history of the name
Halligan was found in the allfamilycrests.com archives. The name Halligan is derived from two distinct Gaelic septs. The O'hAileagain sept was located in Counties Louth and Armagh while the O'hAileachain sept was located in Counties Cork and Waterford.
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.
The sept from Louth and Armagh is noted in records as early as the year 1042 when the death of one of the name was recorded in the Annals of Ulster . In the sixteenth century the name was recorded as O'Hallagan and O'Hollegan in Connaught Province and also as Olligan in County Kildare. Other variants of these Gaelic sept names include Halahan and Hallighan.
The Halligan 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 Halligan descendants.
