My paternal second cousin, Gary David, of Potosi, Wisconsin looks quite similar to Larry David. I also see the resemblance somewhat in my dad. My paternal GGG-GF, Joseph David, Sr was born in Prague, Bohemia, and his son, Joseph David, Jr was born there as well. I was told there was a conversion from Jewish to Catholicism, but I'm not sure exactly how long ago. I'd love to learn more about them and the ancestors before them -- where they lived before Prague.
