Very interesting! That family could well have been Jewish. Amitai's sister's name was Oriane. I just assumed that was a French version of Oriana, but does is it in use in Israel?
I'm in Israel, and:Amitai - My sister says she once saw a girl named Amitai, but I always thought it was generally a boys' name.Oriane - I know a couple of girls named Oriane (Israeli) so yeah, it's used, but I don't think it's very common.Noa
