Bartholomew J. Rockefeller just because there's no way anyone would ever think I'd pass as a man and the name would be funny in contrast. My face is decidedly feminine and I'd be way too lazy to bother to remember to display the non-verbal gestures and behaviors of a man.
Also, Rockefeller is a sick ass last name. Even if they weren't a fuck-you-rich family, still a sweet name.
