I like
Frances and
Francis, and
Frankie, for girls and boys. :)
I'm not a fan of parents naming their children after themselves, regardless of whether it's father/son, mother/daughter, or anything else. I especially don't like it when a man and woman have a son named for the father and a daughter named for the mother. It creeps me out, because then it's like the brother and sister are a miniature version of a married couple. :/
