Neil,
If he is going to have difficulties with pronunciation then you will want to avoid certain letters in the alphabet. Don't worry too much about kids making fun. It is going to happen no matter what. Pronunciation I guess, is why we see so many Asians in western counties with simple names like Peggy. Not so common but easy to pronounce. In my area I see a lot of males named David or Mike.
I had a student last year who immigrated from Israel. His name is David or his mother pronounces it Dahvit. One day I hear a student ask him if he had a donkey when he lived in Israel. David said no that he had 2. Another student kept saying "I just want to know what a dradle is," so David brought several cheap ones to school and told the student all about them. David rolled with the punches. In one years time he became one of the more popular students.
