Origin of the Name Dinneen
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 Dinneen
include Dinan, Dynan, Dineen and Dinane. The name Dinneen is of Gaelic origin and is derived from two distinct Gaelic septs.
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 O'Duinnin sept of County Cork anglicized their name as Dinneen. These were renowned as poets and historians. The O'Daghnain sept located in Counties Cork and Clare also changed their name to Dinneen, as well as the more usual Dynan and Dinan. In the year 1606 in 'Bishop Montgomery's Survey of the Diocese of Raphoe', Dinan is given as the name of the erenagh family of Aghadowney. In the year 1659 this name is recorded as a principal Irish name in the barony of Carbery in West Cork . In County Clare Dinneen was not found to be a principal name at that time but by the year 1821 there were 23 families of the name recorded. Griffith's Valuation of 1851 found the name mainly in County Cork .
The Dinneen 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 Dinneen descendants.
