The History of the Mackenzies
Alexander Mackenzie published his comprehensive genealogical History of the Mackenzies in 1879 and reissued it in 1894 with a considerable number of additions. The text of the second edition, in its entirety, is available in various places online including from the link below. It becomes especially relevant to Lewis on p150 with the arrival of Colin Ruadh, the first Earl of Seaforth, who took possession of the Isle of Lewis in 1610, but is fully text-searchable for other connections.
