First, congratulations! I completely understand, I was in the same boat with one of my pregnancy/babies. It’s hard to let go of, but if it’s not their name, it isn’t their name! And you know!!
I love [name_f]Parks[/name_f] as a mn and the family connection.
Some fn options that came to mind -
[name_m]Bridger[/name_m]
[name_m]Walker[/name_m]
Lawson/Lawton
[name_m]Porter[/name_m]
[name_m]Rhett[/name_m]
[name_m]Grant[/name_m]
[name_m]Tate[/name_m]
[name_m]Holden[/name_m]
Bo
[name_m]Callum[/name_m]
(I feel like I thought of names like [name_m]Miller[/name_m] from your list.) hope this helps!
