MUIRHEAD, MOREHEAD. From one or other of the many localities of the name in the southern counties, perhaps from Muirhead in the barony of Bothwell. The lands and town of Mureheid in the diocese of Ross are mentioned in 1576 (RPC.), but the surname is not likely to have originated there. The first of the name in record is said to have been Sir William Muirhead of Lachope, end of fourteenth century. Probably the same person as William de Murehede who witnessed a charter of lands of Cranshaws in 1401 (Swinton, p. xvii).

Dunk.), David Muirheyd was assizer in Gowane (Govan) in 1527 (Pollok, I. p. 258), and David Mourheid was merchant burgess of Dumfries, 1668 (Inqis., 938). In common speech pronounced Murheed.
