So is Peach the first name, and Toadstool the last? Peach Toad, Princess of the Mushrooms

Seems to be the same deal as Nash/Charlie from Street Fighter Alpha.
He was called Nash in Japan, but Charlie in the west. Then in Street Fighter V, Capcom made his name Charlie Nash in both versions. So Nash is implied to have been his last name.

You're not wrong about how it began, but he was officially made into Charlie Nash waaaaaaaaay before SF5. Like, 10 years before, at least.
