Both Clan Fraser and Clan Mackenzie are real clans in Scotland. In fact, Clan Fraser divided into two clans in the fourteenth century. There was the Lowland Frasers of Philorth and the Frasers of Lovat, of which Jamie was a member. Clan Mackenzie has been around since the 11th century. The Mackenzies did in fact feud for centuries with Clan MacDonald. Clan Mackenzie was one of the most powerful clans in Scotland.
