Georgia,
This is a long-shot at best, but if you take a look at my web page you may or may not find some information that connects:
http://homepages.rootsweb.com/~decann/genealogy/master/I do not see any information that I can say is what you are looking for, but I do show quite a few folks named William
Cann, and one of them has a son named "
Rod," which could be short for Rodney. I show no son named Curtis, though.
Also, be aware the city in
Henry County,
Illinois is Geneseo, and you have the last two letters inverted.
As I said, this is a long-shot at best, but if you see any information that will help you, I will be happy to share it. Perhaps an exchange of GEDCOM files?
