The history of Clan Muir

The Mures of Rowallan were a family of standing in Ayrshire from the thirteenth century, and their marriage into the royal house, Elizabeth Mure to the future Robert II, placed Muir blood at the root of the Stewart dynasty. The name spread broadly through the Lowland south-west, settling on the spellings Muir, Mure and Moir.

Its most celebrated bearer crossed the Atlantic: John Muir (1838–1914), born at Dunbar in East Lothian, emigrated to America and became the founding voice of its conservation movement, co-founder of the Sierra Club and the moving spirit behind Yosemite and the national-park idea. The Orcadian poet and translator Edwin Muir (1887–1959) made it a name in modern literature, while the broadcaster and wit Frank Muir (1920–1998) made it a household one in postwar Britain.
