Ohhh awesome, I love
Atalanta but always feared people would call her Atlanta (well I actually like that too, but if I name her
Atalanta I'd want her to be called
Atalanta). It's a great name.
Aphrodite is a bit much but fine. I guess it's a bit hard for a little girl to carry as it doesn't even come with a more approachable nickname.
I'm not a fan of sibling names starting with the same initial but I think it might have been a coincidence in this case as the other siblings have names that start with different letters.
I find
Cassandra a bit boring, it seems quite common. At least I hear it once in a while.
Kassandra is nice, too.
Victoria is nice but common.
Jason seems trendy and common.
Venus might be a bit much, just like
Aphrodite.
