I found that record also, but there was another one after that I believe that listed Stephen as divorced. It is my guess that they had three children and when they were divorced, she left them with him. A relative said there was speculation that Ana had other children, but nobody knew for sure. This may confirm that suspicion. I figure either the census was wrong, it was reported that way to save embarrassment, or I am completely off base here. Once again, thank you for your help.
