Months ago I wrote "I looked at the 1900 census again. This is the one where Napoleon reappears after being missing (to me) since 1870. A few lines down is his mother and brother Richard. I just noticed that Winnie said all her four children are still living. That means somewhere Hiram and Elizabeth is hanging around just waiting to be discovered.
Napoleon is living next door to his in-laws also. These in-laws are also my ancestors, related to me through Mary Saunders, Napoleon's wife, my great-grandmother. Charles and Rose are a few doors away. It got me to thinking that maybe Elizabeth is nearby. There happens to be an Elizabeth who is the right age living next to the Sanders. I know. I know. That means nothing. But it is a splinter of possibility."
That Elizabeth was married to Sylvester Ames. Not long after posting the above, I found out that Elizabeth's maiden name was Cotten. I was so excited but somehow forgot to post it here. Elizabeth had died by the next census and I have not found out any more on the family.
Hiram has been much harder to find since I don't know which surname he used. One candidate is Hiram Cain in Franklin County, MS. I found a Hiram Anderson in Franklin County, on the 1880 census. He is a servant at the time and single. The hitch is that Hiram Cain claimed he married in 1878 on the 1900 census. It means more sleuthing for me to do.
