Family name origins & meanings
- Scottish : from an Anglicized form of the Gaelic personal names Muire(adh)ach, a derivative of muir ‘sea’ (hence the usual translation as ‘mariner’) and Murchadh ‘sea battler’. These may originally have been patronymics, the prefix Mac having been dropped at a later stage.
- Irish (Ulster) : when not of Scottish origin, a variant of Murtagh.
