Muireadhaigh

Ó Muireadhaigh, Mac Muireadhaigh, and MacMuireadhaigh are Gaelic surnames. They translate as "descendant of Muireadhach" and "son of Muireadhach", respectively, which have been anglicised as Murray and Morrow in southwestern Scotland, northeastern Connacht and County Cavan.

The name Morrow is found primarily in Counties Donegal, Antrim, Down and Armagh which is due to Scottish settlement in those areas.
