I have a problem placing Samuel in this family - If John and Mary's ages as 54, in 1850 were correct, I doubt that they were having a child as early as 1812. Perhaps Samuel was instead a younger brother to John. Definitely more research needed. Some online databases have solved this by backing up the ages of John and Mary by 10 years or so.
