I don’t think most people will know the meanings of [name_m]Corbin[/name_m] or [name_f]Mavis[/name_f] so I think they match in a subtle way. It’s not like you’re naming them [name_f]Raven[/name_f] and [name_m]Sparrow[/name_m].
[name_f][/name_f]I think you could certainly continue the bird theme with siblings, or add in other nature-related names.
