I mentioned this to SapphireSkylines, who had taken up a twin-sister character a little while back but that stuttered out... but unfortunately due to her background (which interweaves with a couple others), she really couldn't do a younger sibling. I was going to suggest maybe another member of the now-defunct tribe or something similar, but you specifically mentioned a sibling... 
In either case, we both wish you the best of luck in finding someone to do this sort of RP with!
