What are the two most common American first names that are also the name of a country (in English)?

The name must exactly match the common English-language name of the country. "Frank" for "France," for instance, doesn't count; but if there were lots of Cubas running around (rather than just Gooding Jr.), it wouldn't be a problem that they are named Cuba rather than Republic of Cuba.

If you want to look up the answer, rather than just guessing, see this file and this one.
