However, there have been several cases where a descendant through the maternal line has changed their surname in order to claim the chiefship of a clan, such as the late chief of the Clan MacLeod who was born John Wolridge-Gordon and changed his name to the maiden name of his maternal grandmother in order to claim the chiefship of the MacLeods.

This concept was where all clansmen recognised the personal authority of the chiefs and leading gentry as trustees for their clan. The second concept was the wider acceptance of the granting of charters by the Crown and other powerful land owners to the chiefs, chieftains and lairds which defined the estate settled by their clan.

From the beginning of Scottish clanship, the clan warrior elite, who were known as the ‘fine’, strove to be landowners as well as territorial
