About the canon relationships thing.

I know that having long lost relatives and brothers and sisters and all that jazz is a bad idea. But, would a distant cousin or something like that be acceptable? Like, say Sonic is told he has this cousin in some other place he hasn't heard about, and they haven't interacted much due to being in different faraway places or some other reason. I'm thinking it's possible to not get in the way of other characters being touted as Sonic's "only remaining relative" or whatever.
