Please rank my baby names

I am having my second child in October and we have a couple names we like so far. Looking for which you like better of the below ideas and also if anyone has any suggestions!

Background: we have 1 son named Elijah (family sometimes calls him Eli). Our last name is 3 syllables and derived from a Gaelic surname (think MacCowan or Flanagan). I was born in the U.S. and my husband was born in Jamaica, we currently live in the U.S.

Boy ideas:
Edison
Ian

Girl ideas:
Molly
Maeve

Open to other suggestions! TIA. Also wanted to add that I’ve always really liked the idea of another E name for my second.
