Origin of the Name Donnellan
The
Donnellan family history 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 Donnellan
include Donelan and Donlon. These Irish names are derived from the Gaelic O'Domhnallain sept who were of the Ui Maine. They belong by origin to the south-eastern part of County Galway where the place-name Ballydonnellan perpetuates their connection with the district between Ballinasloe and Loughrea. A Donnellan Archbishop of Tuam translated a great part of the New Testament into Irish . He was the direct descendant of the Chiefs of the name, of Ballydonnellan, and ancestor of the Donelans of Sylanmore in Tuam. Other minor septs of O'Domhnallain were located in Counties Offaly and Tyrone, although the majority of modern descendants of Donnellan can still be found in the County Galway area.
The Donnellan 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 Donnellan descendants.
