[name]Fionn[/name] sounds to me exactly like the Welsh girls’ name [name]Ffion[/name], I thought you’d made a typo of that at first… [name]Finn[/name] or [name]Flynn[/name], or even [name]Ian[/name], all sound similar but more masculine to me. That said, I’ve never heard of the boys’ name [name]Fionn[/name], so maybe it is a legit name and I’m just not familiar with it.
My favourites from your list are [name]Declan[/name] [name]Roscoe[/name] and [name]Tristan[/name] [name]Beckett[/name]. [name]Cato[/name] is too Hunger Games for me and [name]Roscoe[/name] I find too surnamey as a first name, though I do know quite a few people with the surname [name]Roscoe[/name] which might explain it.
I love [name]Tristan[/name]. Not too crazy about [name]Beckett[/name]. However, I think it’s the best combo on your list. [name]Fionn[/name] [name]Roscoe[/name] is in second place.
The two I would vote for are the most popular; [name]Tristan[/name] [name]Beckett[/name] and [name]Declan[/name] [name]Roscoe[/name], which are both very handsome.
I love [name]Cato[/name] but I don’t like it with any of those middle names.
