[name]Wesley[/name] and [name]Sloane[/name] are both really nice name. Im not sure about using [name]Dean[/name] and [name]Martin[/name] in the same name given the connection (unless thats what your going for) but I like both names seperately.
I love [name]Sloane[/name] for a girl! I agree with the pp about [name]Martin[/name] and [name]Dean[/name] in the same name, though. But if they are particularly meaningful to you, I say go for it.
[name]Dean[/name] was actually a very close of mine that recently passed, and [name]Martin[/name] is a family. So while the connection was there it was kind of unintended.
