Struggling with baby names...need help!

This is my third baby...and all my babies we didn’t find out the gender until birth. I can’t quite get excited about any of the names I have written down. I am thinking maybe I am not excited about the names bc i have not met the baby??? Here are our current children’s names and any advice or suggestions would be appreciated. Baby is due in August 2020.

Daughter- Lucy

Son - Jack

Names we have liked for girl:

June

Mariel

Elena

Names we like for a boy:

Jesse

Walter (Walt for short) also family name

Max (love max but my husbands cousin who we don’t see other than every few yrs is named this)
