I like [name_m]Atticus[/name_m] the best, but I’m not sure about it with your surname.
[name_f]My[/name_f] second pick would be [name_m]Horatio[/name_m].
[name_m]Atticus[/name_m] [name_m]Julian[/name_m] is my favorite, but I think it has too much of a heavy “k” sound with your surname. What about [name_m]Julian[/name_m] [name_m]Atticus[/name_m]? [name_m]Stuart[/name_m] is nice, but it feels to abrupt and short with your last name. What about [name_m]Felix[/name_m] [name_m]Stuart[/name_m]? Although I’m not crazy about [name_m]Horatio[/name_m], it definitely flows the best with your last name.
I love [name_m]Horatio[/name_m], and I like [name_m]Felix[/name_m], so [name_m]Horatio[/name_m] [name_m]Felix[/name_m] is perfect! I’d love to meet a little [name_m]Horatio[/name_m] in real life.
