I love finding the tidbits and telltale signs of a family from one generation to another. I have always enjoyed noticing who has whose hands, feet, demeanor, eyes, bone structure, or personality. It's like working a puzzle only backwards to me. Meet Carl Van Hook. [Kenny's maternal grandfather]

Now meet his great grandson, Casey McGill Cobble.
