Mars is a name with interesting potential, ticking the boxes as a mythological name, a space name, and a single syllable choice ending in -s.

Any number of Fitz names -- Fitzgerald, Fitzpatrick, Fitzroy, Fitzwilliam -- have been used as Christian names, in fact Fitzwilliam was the given name of the dashing Mr. Darcy in Pride and Prejudice. Fitz can be a short form of any of them and is often, like Mac, a nickname drawn from a surname.

Irving Berlin changed his name from Israel; actor Ving Rhames streamlined and coolized it. Irving was a Top 100 name during World War I, and though we don't envision it reaching those heights again, we can see some hipster parents having their own little Ving.
