Most people have a fairly good idea of who they are and where they come from.
The traditional family structure is typically in place, with family members across the board getting together at some point in their lives: parents, brothers, sisters naturally. Grandparents, usually. Great-grandparents becoming a bit more rare, but still often seen. Cousins, uncles abound. Great-great-grandparents can be a bit tougher to gather for a party – but it certainly could happen. Going back in time further than that generation, you’ll rely on geneology records and stories handed down throw family’s joint recollections.
