Origin of the Name O'Connor
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 O'Connor
include O'Conor, Connor, Conor and Conyers. The O'Connors descended from Conchobbar who was King of Connacht in the year 971. The last two Kings of Connacht, Turlough O'Connor, 1088-1198, and Roderick O'Connor, 1116-1198, were of this line. There were six O'Connor septs, the most important being the O'Connors of Connacht. The O'Connor sept of Kerry had their territory north of Kerry, but were pushed to the Shannon estuary after the Anglo-Norman invasion of 1170. The other septs were O'Connor of Corcomroe, Clare, O'Connor of Offaly and O'Connor of Keenaght, Ulster. Their family mansion in Clonalis, near Roscommon, is a unique treasury of Irish relics.
The O'Connor 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 O'Connor descendants.
