That's an interesting observation! I seem to have patterns for the names of my characters. One pattern is double letters:
Julliah, Sarriah, Arrayah, Suuzanne, Allanna
These last two were more to have support fuctions in SWG, I never intended to RP with them, but they ended up with storylines. Allanna is the featured character in a book a friend is writing about an X-Wing Cadet. He did it as a 'thank you' for a favor I did for him.
Suzy, because RP fodder when I'd wanted to see if I could play a mean, nasty character. She is an Imperial Intel Agent. LOL, I'm not really too good at the mean nasty characters.
To the original question, I hadn't thought about the H being for second characters, but in a round about way, they are.
Also, I'm considering the chocolate theme. I have so much fun with it with my other two characters.
