I adore the name
Georgina. If you are asking whether those listed names would fit as a mn, then only Gerogina
Minerva, being the only girl's name, would work. It's a fun, sophisticated combination. I knew a
Geordie once who was a guy, and I didn't like him at all. It's hard for me to think of
Geordie on a girl, but why not? As long as it's just a nn and she has
Georgina to fall back on.
The other names,
Aubrey,
Hamish and
Caspian, would make great brothers to
Georgina Minerva.
