I don't have a thing more on John Riley - all I have is the one census listing him - but do get in touch with me and maybe we can figure something out.
I have Jonathan in 1850 and 1860, I have his marriage to Nancy Jane Conner, his divorce and remarriage - and then I lose him.A lot of his family shows up in Wayne County, Illinois, and in fact he is buried there, but I haven't found anything more about him.
I've sent for his pension info, and maybe that will tell me something, but if you know where John Riley was, that could help too.
I do have some info on Jonathan's parents and grandparents -
