With Troy you’d have an ancient place theme, which would be fine (just something to consider). Personally, I would choose either Nicholas Troy or Nicholas Joaquin as a brother for Roman David. I love their vibe and the potential nicknames. All of your names would sound lovely though. What name do you want to hear everyday? That’s what I ask myself lol
[name_u]Troy[/name_u] [name_m]Nicolas[/name_m] I feel like [name_u]Troy[/name_u] is one that’s grown on me and one I associate with you/your naming process so it feels right!
[name_m]Joaquin[/name_m] [name_m]Nicolas[/name_m] & [name_m]Nicolas[/name_m] [name_m]Joaquin[/name_m] are both so beautiful!! with [name_m]Roman[/name_m], I slightly prefer [name_m]Nicolas[/name_m], especially if you plan on using Nico!!
