Origin of the Name Mulholland
family history was found in the allfamilycrests.com archives. The name Mulholland has a wide number of variants including O'Halohan, Holland, Houlihon, O'Holohan, Houlihan and Hyland. These names are mainly derived from two Gaelic septs. The first was the O'Maolchalann sept, meaning 'devotee of Saint Calann'. The second was the O'hUallachain sept which is more usually anglicized as Holland and Houlihan. The former sept was of Loughinsholin in County Derry where they were the keepers of the bells of Saint Patrick. The septs of Demifore in County Westmeath and of Ui Fidhgheinte were of importance in mediaeval times but have faded over recent centuries. In Offaly the O'Holohans shared the leadership of the Clan Colgan with the O'Hennessys. It was one of these, Dermot O'Holohan, who constructed the curragh bridge across the Shannon above Portumna which enabled O'Sullivan Beare to cross into Connacht on his epic march from Kinsale in 1602.
The Mulholland 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 Mulholland descendants.
