My godmother is pregnant

I'm helping her to find a name for their baby. They know the sex, but haven't told anybody yet. So, they have 4 beautiful little girls and one boy.
May Dawn 9
Ann Esme 8
Gia Venice 5
Eve Kylie 3
Max Tennyson 1
They want a 3 letter name. These are the only names I can come up with! For a girl they are planning to give the middle name Spring. Mother's name is Joy and dad's Ben (Benjamin)
Kay
Ava, but is it too close to Eve and Ann?
Joe
Ray
Zac
Any suggestions? Thanks so much!
