Names with the second letter "a" and/or 4 syllable names

Mahmah3

Looking for boy and girl suggestions. We already have James, Hannah, and Madeline--all family names, happen to have a second letter "a", and have 1,2,3 syllables. I'm not sold on our names that we have picked out yet and we only have maybe 6 weeks left.

We have a family name for a boy, but I'm not sure about a surname as fn and it rhymes with Madeline. Flynn William.

We have girl names we like, but have no significance except mn. Emily Jane. Julia Fern. And I could get dh on board for Olivia bc I like it, but he's eh about it.

I don't know how you come up with such extensive lists, but thanks! I've mentioned some of these before to dh, but can't get him on board. Names just aren't easy for me this time around.
