Murtagh History, Family Crest & Coats of Arms 

Origins Available: 
  Ireland 
  Scotland 


While many Irish names are familiar, their past incarnations are often shrouded in mystery, reflecting the ancient Gaelic heritage of their bearers. The original Gaelic form of the name Murtagh is Ó Muircheartaigh, which is derived from the word "muircheartach," which means "navigator."

Early Origins of the Murtagh family

The surname Murtagh was first found in County Kerry (Irish:Ciarraí) part of the former County Desmond (14th-17th centuries), located in Southwestern Ireland, in Munster province.

"The name Moriarty is now largely represented in County Kerry, in which county the O'Moriartys were Chiefs in the Barony of Dunkerron." 1

The fictional Professor James Moriarty in some of the Sherlock Holmes stories written by Sir Arthur Conan Doyle was based on Doyle's discussions with a Scotland Yard inspector and his knowledge of Adam Worth (1844-1902), the German-born American criminal mastermind.

Murtagh Spelling Variations

Irish names recorded during the Middle Ages are characterized by many spelling variations. This preponderance of variations for common names can be explained by the fact that the scribes and church officials that kept records during that period individually decided how to capture one's name. These recorders primarily based their decisions on how the name was pronounced or what it meant. Research into the name Murtagh revealed many variations, including Moriarty, O'Moriarty, Murtagh, Murtag, McMoriarty and many more.
