I think [name_m]Phineas[/name_m] is a solid choice, maybe [name_m]Phineas[/name_m] [name_m]Linwood[/name_m] or [name_m]Phineas[/name_m] Lionhart?
Maybe (assuming you don’t want to repeat letters) :
[name_m]Justice[/name_m] [name_m]Isaac[/name_m]
[name_m]Oswin[/name_m] [name_f]Beloved[/name_f]
[name_m]Prosper[/name_m] [name_m]Joah[/name_m]
[name_m]Conner[/name_m] [name_m]Theon[/name_m]
Hopefully these help
