I really like [name_m]Vincent[/name_m] and [name_u]Sullivan[/name_u]. [name_u]Sullivan[/name_u] is punchy with the surname vibe of [name_u]Carson[/name_u], while [name_m]Vincent[/name_m] is underused and stately IMO. I think [name_u]Vinnie[/name_u] or Vincie would be really cute for a little one.
[name_u]Sullivan[/name_u] and [name_u]Luca[/name_u] are my favorites by far.
