"Who's your family?" Southerners know this greeting well, but it is not unheard of above, beside, and around the Mason-Dixon line. Many people value roots -- where you come from, who your people are, what constitutes "home." We speak of those who are "rootless" as unfortunate; those who "wander" are aimless and unfocused. Adopted children search for their birth parents because they want to understand their identity, and to them that means more than how they were raised and what they have accomplished -- heritage counts. Clearly, we place a high value on origins, birth, and descent.
