I'm not a proponent of respelling normally, either. But for some reason...*shrug*
I usually pronounce
Lucia Loo-See-eh. Which is funny, because that's how people always try to pronounce MY name, and I have to correct them. I don't really like
Louisa.
Louise is my mom and my grandma's middle name, and neither of them really liked it. Primarily for the nickname Wheezy, which stuck to both of them!
I do, however, like
Lucinda. I waffle back and forth, loving it and liking it.
