Clan Muir is a Scottish clan that is armigerous. Per certain sources, holders of the surname Muir (also appearing as Mure and Moore), of Ayrshire, have been noted as a possible sept of Clan Boyd, though this is not clearly identified to a reliable resource.^[37] A spelling variation More/Moore is a sept of Clan Leslie in Aberdeenshire, and, having genetic proof of Muirs in Aberdeenshire, may have roots in the Mure/Muir line of southwest Scotland.^[38]

However, there are other instances in which links to the Mure/Muir line of southwest Scotland cannot be confirmed. The surname Moir, for example, is a sept of Clan Gordon in the highlands, but is not part of this same group of Mure/Muir/Moore.^[39] A single family, the Mores/Moores of Drumcork, are septs of Clan Grant, but there is no evidence of a connection to the Mure/Muir line.^[40] Some also project Muir may be a sept of Clan Campbell, though even Clan Campbell considers this unlikely.^[41]
