Small villages where everyone is a relative are very common in the recent past. In same places it is still the case. Modern man has up to 1000 "relatives" for sure. It just happened to be people who don't care about that person or not even aware he or she exists (celebrities for instance) I heard about Dunbar number from pop-science articles, and it feels right. Isn't Marines companies size based on this number? Must be true then.
