[name]Clinton[/name] goes well with [name]Spencer[/name]. Also, [name]Clint[/name] is a fantastic nn.
I think I would stick with the “surname” as first names theme. I was also thinking British possibilities as [name]Spencer[/name] is the surname of Lady [name]Di[/name]'s family. [name]Windsor[/name] (the [name]Royal[/name] families surname) or [name]Winston[/name] (as in [name]Churchill[/name]) are nice possibilities.
