June, Assuming you have the right person, it sounds like a typical case of getting a girl pregnant, running away and then moving constantly to stay one step ahead of rumours, in-laws, authorities or perhaps even creditors. Soon the attraction wears off, and they find other partners Have you found registrations of the marriages or various births of children? I wouldn't rely on just the census. I presume you looked at all possibilities for Henry Hart and Henry Hayden born around 1853. I would look further afield than just one county. It's very easy to focus on just one "Bill Smith" when logically there are hundreds in any time frame or location. And if you restrict search criteria to exact matches on 1853 and Brighton, you're only looking at one possibility. Peter
