|Duke of Wellington|
Dukes are popular. We authors of historical romances create hundreds of them, contrary to historical fact. In the 1816 Debrett's, from which I've clipped the summary about this rank of the peerage, I count only 18 English dukes. This includes the brand-new Duke of Wellington.
You can learn about the privileges of being a member of the peerage here.
