Who ARE all these people?

Beats me, but somehow I think if DNA samples were taken a connection might be determined.

Mary spent the day trying to determine who were cousins once removed, who were second cousins (and what the difference was), who were sisters/brothers, etc. etc. Luckily she had met Uncle Jules when she first arrived so at least she had that relationship figured out before the day began. She never realized she had so many east coast relatives.
