Birth registration was not compulsory until 1875, from 1837 to 1874 the registrar toured the district getting notes on new births and even in rural areas, some were missed, or even if they were registered, some may have not made it to the GRO index. Have you tried the local RO for John Thomas Horton's birth? Have you got his mum's maiden name, such as her marriage cert?
