However, their descent can only be proved by contemporary evidence back to a Robert de Munro who died in 1369.
[1] According to 19th-century historian Alexander Mackenzie, the chiefs of the Clan Munro are from as early as the 12th century designated Barons of Foulis.
Strictly speaking Robert Mor Munro (d.1588) who Mackenzie designates the 15th Baron was the first true Baron although the Munro chiefs had previously held their lands from the Earl of Ross and directly from the crown for centuries before that.
It has been claimed, although not proven that because the Munro of Culcairn family was living in London, England, it was assumed that they had died out, even though they had not.
Their son, Patrick, took his mother's maiden name, Munro, in order to become chief of the clan.
