What's in a name?

I've nicknamed the snail of mine who has an egg sack on his shell "Spooge," but we decided he should have a proper name for when the egg sack has long since gone away. I settled on Winston for a first name, but needed to come up with a really great last name for him because I wanted him to have roman numerals on the end. At work we were discussing some naming options and were trying to think of what the British royal family's name is and realized they don't have one. The closest thing they have to a last name is "of Whales." So, after much balking at the british royal family I settled on a name for Spooge:

Winston "of Whales" Mountbatten-Windsor IV
