Hello, I don't know if I have much to offer you but I am a descendant of the Davis Benjamin Clawson you have listed on this site. He was my gg-grandfather. Harry Alfred Clawson was my g-grandfather, Alfred Bruce Clawson was my grandfather, and Bruce Alexander Clawson is my father. I have a lot of information on the Clawsons and other lines in my tree but not necessarily much on the Caldwell line. If you want to take a look at what I have, my site is at http://go.to/ClawsonGenealogy. There are also pictures of Davis and his children.
