Earl of Rothes

The Earl of Rothes was a title given to the ruler of Leslie, starting with George Leslie in 1458, given the title by James II of Scotland but has now evolved to a completely hereditary title since the local council now rules Leslie and has since around the 1950's. The title is mostfamous for being given to Norman Leslie, husband to Noel Leslie, a titanic survivor who died in 1956.
Another title given to the Earl of Rothes from 1445-possibly 1773 which was Lord Leslie but even then was a hereditary title to show their success in the Leslie family and Clan Leslie/Rothes.
