[name_f]My[/name_f] Top 5:
[name_m]Zachariah[/name_m]- I always thought this was such a friendly sounding name. I prefer [name_m]Zachary[/name_m], but [name_m]Zachariah[/name_m] is still lovely.
[name_u]Sinclair[/name_u]- I think this is such a great name. I imagine a [name_u]Sinclair[/name_u] either being quiet and studious, or a total spunk.
[name_m]Aston[/name_m]- I love [name_m]Aston[/name_m] [name_m]Martin[/name_m]'s, I love the sleek but friendly sound, I love the vague astronomy connection. [name_u]LOVE[/name_u], in big letters.
[name_m]Franklin[/name_m]- Probably my favourite on your list, on parr with [name_m]Aston[/name_m]. [name_m]Franklin[/name_m] is just such a wonderful, jazzy cool name.
[name_m]Julius[/name_m]- I know a kid called [name_m]Julius[/name_m], and honestly, he has made me love this name.
Very Favourite Names: [name_m]Franklin[/name_m] and [name_m]Aston[/name_m].
