Muireadhach is Gaelic in Origin.

Muireadhach is a masculine Goidelic name, attested in Old Irish as Muiredach and in Scottish Gaelic as Muireadach. Most scholars connect it to muir “sea” with the adjectival/agentive suffix -each/-ach, yielding a sense like “seaman” or “of the sea,” though medieval glosses sometimes treat it as “ruler/chieftain.” The genitive Muireadhaigh underlies Irish surnames such as Ó Muireadhaigh, later Anglicised Murray and Murry in Ireland (distinct from Scottish Murray of Moray origin).

The name was borne by numerous early medieval figures, including kings (e.g., Muiredach mac Brain of Leinster) and churchmen; St Muiredach’s High Cross at Monasterboice commemorates an abbot of that name (d. 923). In Scotland it persisted as Muireadach and the contracted Muireach, producing Anglicised forms Murdoch, Murdock, and the given name Murdo. Variant spellings include Muireadhach, Muiredach, Muireadach, and Muireach, reflecting regional and historical orthography.
