[name_u]Phoenix[/name_u] - b
[name_u]River[/name_u] - b
[name_u]Wren[/name_u] - g
[name_u]Blaze[/name_u] - g (only because the only [name_u]Blaze[/name_u] I know is a girl but I can actually see it on both)
[name_u]Royal[/name_u] - b
[name_u]Sydney[/name_u] - g (but [name_u]Sidney[/name_u] is b)
[name_u]Indiana[/name_u] - g (but could work on b with the right combo)
[name_m]Reef[/name_m] - b
[name_u]Forest[/name_u] - b
[name_u]Phoenix[/name_u] - could be either a girl or a boys name
[name_u]River[/name_u] - boys name
[name_u]Wren[/name_u] - boys name
[name_u]Blaze[/name_u] - boys name
[name_u]Royal[/name_u] - boys name
[name_u]Sydney[/name_u] - this is a girls spelling
[name_u]Indiana[/name_u] - girls name
[name_m]Reef[/name_m] - boys name
[name_u]Forest[/name_u] - boys name
I agree with @river_dweller most of these feel very neutral to me, with the exception of [name_u]Wren[/name_u] and [name_u]Blaze[/name_u]. These are my preferences:
[name_u]Phoenix[/name_u] - b
[name_u]River[/name_u] - b (but I love this one on a girl too)
[name_u]Wren[/name_u] - g
[name_u]Blaze[/name_u] - b
[name_u]Royal[/name_u] - b
[name_u]Sydney[/name_u] - g (but like others said, [name_u]Sidney[/name_u] for a boy)
[name_u]Indiana[/name_u] - b (love the nn [name_u]Indy[/name_u], and Indiana/Indie for a girl)
[name_m]Reef[/name_m] - b
[name_u]Forest[/name_u] - b
