Origin of the Name Costigan
The origin of the name
Costigan was found in the allfamilycrests.com archives.
Over the centuries Surnames developed a wide number of variants. Different spellings of the same name can be traced back to an original root. Additionally when a bearer of a name emigrated it was not uncommon that their original name would be incorrectly transcribed in the record books at their new location. Surnames were also often altered over the years based on how they sounded phonetically and depending on the prevailing political conditions it may have been advantageous to change a name from one language to another.
Variants of the name Costigan
include McCostigan, Costagan, McCostigane and McCostygyn. These names are derived from the MacOistigin Gaelic sept whose native name was later altered to MacCostagain. This sept were a branch of the Fitzpatricks of Ossory and were located in the Leix area.
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.
An early record of the name occurred in the year 1540 when a Patrick MacCostykyen was a Juror in County Kildare. In 1544 the name is recorded in a list of Irish Kern mustered by the Earl of Ormond. In a deposition in 1650 a Dermot O'Costigan was a recorded as a dispossessed gentleman turned rapparee. The main families of Costigan were largely unaffected by the attempted plantation of Leix and Offaly and retained their ancestral seat until the seventeenth century. In modern times this name and its many variants are still well represented in Counties Offaly and Laoise.
The Costigan 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 Costigan descendants.
