I've looked everwhere for this family. There is William Jarvis born abt 1788 in Ordsall Nottinghamshire and wife Mary 1784 Clarborough Nottingham, son Henry born 1826 Tickhill Doncaster Yorks, daughter Mary 1823 Tickhill Doncaster. In 1851 William and wife can be found in Scrooby Nottinhamshire. I found 2 Henry Jarvis in Doncaster/Rotherham but neither fit as one with wrong parents and the other is in a deaf and dumb school. Henry was in Bawtry in 1848 when he was married to Ann Teasdale. Both Henry and his father were agricultural workers.
