Frank, Frankie, Franklin (and Norman)

In rounds of this type, where the answers all share a forename (or two), it's fair enough to include some variations on the basic name or names. But if you're going to do this, you should include a note at the start of the round to warn contestants.

Frankie Howerd was easy enough, but Franklin B. Pierce is a bit more obscure and required a degree of lateral thinking.
