Jean C. Thank you for your comments.
I dont think John BACK is the right person. All his Sisters and brother are all listed as BACK (Anne 1806 ;Eliza 1808 John 1810 and Henry 1815. The marriage register of the marriage states John Beck bachelor with consent Ann Cannell of thgis parish. Does this mean he was under 21. If so the John Beck born c1812/3 as per the ages in the cenus would be correct. All I have to do now is find out his parents as I am not sure as to the John Beck and Mary Hastings.
