I think it is a very pretty name - someone I work just had a baby and named her Peyton Anne. Isabella is classic and you could always use Bella for short. I try to think of the nicknames when I picked the names out for my children, because sometime along the way someone is going to shorten to something. I also like unique and timeless classic beauty names - I have 2 boys, Kyran Anthony (wanted Anthony for a first name, but didn't want it to be shortened to Tony) is 9 (sounds like Ky-rin), Isiah Robert (Robert after my husbands grandfather and roll model) is almost 4 (after Isiah Thomas - my husband is a Pistons fan) and my daughter Arianna Raechel (we pronounce Ari-anna not like Ariel), I found her name in the menu name of a salad at a coney island on my due date - she was 3 days late and we only had boy names, didn't know what we were having. I also like to look up the meanings of the names too.
Anyways - I think that Isabella Peyton is beautiful.
