Correction:

What I meant to say that if my theory is correct, given the popularity of "James Bond double 007, it's interesting that "James" wasn't used as a source for multiplicity of male and female names.
{Of the top of my head I can think of the name "Jamesetta", and "Jamie" {both female} but not others.

Obviously, "Sean" would be used as a base for "Shawn" names...

:O)
