Baby names

So I know I will only be 10 weeks tomorrow, but I'm already a muddle with baby names: I like more traditional names and want one that will fit with my other children and step-kids names. As dh got to name our last baby, the decision is mine this time! ha ha.
Our children's names are: Katie, Thomas and Luke and my step-sons are Daniel and James.
We aren't going to find out the sex of the baby until it's fully cooked and is delivered.

Choices for a girl: Bethany, Anna, Holly, Lucy (dd likes Lucy but I'm not sure), middle names for definite will be Elizabeth May. I honestly don't know right now which, any other suggestions greatly received.

Choices for a boy: Jack, Liam, Ethan, Peter (as suggested by ds1, is my dads name too) middle names not yet 100% worked out, but was maybe thinking Ethan Alexander as 2 potential middle names, again, any other suggestions greatly received!

This really does get harder the more children you have! Never thought I'd say that!

I like Anna for a girl and Jack for a boy. :-)

I like Bethany and Holly for a girl, and I like Liam and Ethan for a boy. If Lexi had been a boy I wanted to name her Ethan Jace, so I guess I'm biased.
