The origin of the name O'Mahoney

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'Mahoney
include O'Mahony, Mahoney and O'Mahony. When Gaelic names were anglicized during the sixteenth and seventeenth centuries they were often changed to Anglo equivalents that sounded most like their original Gaelic name. Their territory was the barony of Kineelmeaky which extended to the sea, where they had a fortified castle called Rosbrian off the coast of West Cork . Mathghamhan, whose mother Sadhbh was a daughter of Brian Boru, was the O'Mahony's ancestor. He was killed with many of his men at the Battle of Clontarf in the year 1014. Another famous bearer of the name was Count Daniel O'Mahony, General of the Irish Brigade in the service of France and hero of the battle of Cremona.
The O'Mahoney 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'Mahoney descendants.
