Ahhh all three are great!
[name_f][/name_f]I’m immediately drawn to [name_m]Finnegan[/name_m] I think he’s gorgeous so whimsy and distinguished with a dark academia flair. I also love boyish [name_m]Finn[/name_m]. However appreciate he doesn’t have the familiar classic feel off H3nry & Carolin3.
[name_f][/name_f]This leads me onto your favourite option the ever dependable [name_m]Oliver[/name_m]. He’s a very soft, handsome and has a tranquility surrounding him. I think [name_m]Oliver[/name_m] does feel in keeping with your older kiddos and I feel with the nickname not being four letters changing up the spelling would resolve that. Maybe [name_m]Olly[/name_m] or [name_f]Olli[/name_f] would work? I really like [name_m]Olly[/name_m].
[name_f][/name_f][name_m]Malcolm[/name_m] is a lovely name that feels stoic and righteous. I think [name_m]Malcolm[/name_m] sounds gorgeous with your kiddos the right feel for sure. [name_m]Mack[/name_m] is also a great nickname. However I do just prefer [name_m]Finnegan[/name_m] + [name_m]Oliver[/name_m]. All three though would be great
