Bettye, I had thought maybe James D. was the son of Richard. When I checked the 1840 Audrain County, Missouri, census, it seemed to fit. As I remember it, William did not. I have some information on this family - census, burials, etc. - because I am trying to find an Elizabeth Dollins who was married to Daniel Rice Moberly in Dallas, Texas, from about 1902 - 1920.
Would you like for me to email what I have? I think I'm good on James D's family, but the rest of the Audrian County Dollins are driving me nuts!
