Origin of the Name Doolan
The
Doolan family history was found in the allfamilycrests.com archives. The name Doolan is derived from several different Gaelic septs. In Connaught Province it is from the O'Dubhlaing sept who also anglicized their native name as Dowling. In Munster Province it is from the O'Dubhlainn sept, taken from the Gaelic word 'dubhshlain' meaning 'challenge'. The O'Dobhailen sept of County Galway also anglicized their name as Doolan as well as Dolan. This ancient sept was located in Clonmacnowen barony in County Galway and in the barony of Athlone in County Roscommon. 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.
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 Doolan 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 Doolan descendants.
