Mullen, Mullane, Mullan, Mullin, Mullins, Ó Maolláin
The name Mullen, and its variations, can have a number of different origins. It may be the Anglicisation of Ó Maoláin, which comes from the Gaelic word “maol”, meaning ‘bald’. The Galway clan of Mullen claims descent from Maolan, who was descended from the King of Connacht. Others may be related to the Scottish MacMillans, which was adapted to Mac Mullan, or to the English Mullins.
