His wife is Kerah, and she's a Redguard.

And I'm sure the Stormcloaks would have no qualms about letting humans into their ranks (though I'd assume they'd be iffy about Imperials). Proventus' daughter (can't remember her name) says (after you take Whiterun with the Stormclaoks) that she would have run out of business if her husband wasn't a Nord. So maybe there were very very few exceptions.
