Jorja is so awful :( I'm sorry. It doesn't even look like the parents were being creative, it looks like they couldn't spell
Georgia. I like
Georgia but find it a bit harsh.
Georgina is more elegant, in my opinion.
I dislike the nickname JJ I think it's really 80s. I know quite a few girls with this nickname, born in the 70s and 80s, whose full names were
Jennifer Joanne,
Jessica Joy and other common J names popular at the time (I feel like the letter J is out of style in general, the only J name in the top 100 for girls is
Julia and that will likely fall out soon).
Jorja nn JJ might make sense, but when people hear
Jorja they will likely assume it was spelled
Georgia and then they will probably wonder where JJ comes from because that's really not a nickname you associate with
Georgia.
