I'm guessing your name is Robert > Bob or Rob
Or maybe Daniel > Dan

I've played through a few times, and I've used different names each time, my most recent trip:

Fighter Hannah daughter
Theif Chiono me
WhiteMage Cari wife
BlackMage Keeli daughteryettobeborn

sometimes I use friend's names, when appropriate. For instance my friend kenneth is a freakin con-artist so I usually name theives Kenny.
