Naming Nuances

This is my hubby's first baby, my third. He is thrilled, obviously, to finally have his own. If it's a boy, it will be named after him, Francisco Ramiro Rodriguez III... the baby being the fourth. However, if it's a girl (my first girl), he wants to name it something I abhor: Adrestia Patience Rodriguez. Ugh! This child will have to live with this name for the rest of its life with no one knowing how to spell it. I have a similar situation, as my name is Christa, and everyone wants to spell it Krista. How will people react to this name? Should I just let him name it whatever, since this is his first child? Will it grow on me?
Thanks in advance,
Christa
