Duncan MacLeod was born in 1592 during a battle in Glenfinnan, Scotland. A foundling, as all Immortals seem to have been, Duncan was born to a Boer woman who had been part of an army engaged in attacking the Scottish Highlands. The newborn Duncan was adopted by Ian MacLeod, the chieftain of the Clan MacLeod, and given to his wife Mary to replace the stillborn son she had delivered. Duncan, as the chieftain's son, was raised to be Ian's successor.
