Thank you all for your suggestions on my Cadwallader family. I think Gloria may have found one of them (William) in Tippecanoe, Henry County, Iowa. I have also been told that William's sister Rachel was married in Henry County, Iowa about 1855, but I have not been able to find a Cadwallader family there in 1860. Thank you very much for all your help. I have never had such a quick and thorough response as on this list.
