[name_m]Emmett[/name_m] and [name_m]Cedric[/name_m] get my votes, with [name_m]Simon[/name_m] being a close third! They feel similarly soft and cozy like [name_m]Hollis[/name_m] and [name_f]Blythe[/name_f] do, with that touch of chic vintage flair. I don’t mind [name_m]Abram[/name_m] or [name_m]Roman[/name_m] either, they’re just a bit harsher in sound for me than your other kiddos’ names!
[name_f][/name_f]Maybe something like [name_m]Rome[/name_m] or even [name_m]Rowan[/name_m] could work as an alternative to [name_m]Roman[/name_m]? Perhaps they’re a bit different from your style (though I think [name_m]Rowan[/name_m] matches with H and B’s names beautifully!), but they feel just similar enough, while knocking out the worry about the name being too “Catholic-y”
