Origin of the Name Dennehy
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 Dennehy
include O'Dennehy, Denehy, Denny and Deeny and these names are all anglicized forms of the native Gaelic O'Duineacha. This sept was located in Counties Cork and Kerry .
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 earliest reference to the name relates to a Donall O'Denaghie of Cloghlea, County Cork , who in 1585 is described as 'vestarius', meaning 'keeper of the vestry'. In the Eastern part of county Cork the name Danagher has been changed to Dennehy.
The Dennehy 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 Dennehy descendants.
