Thank you Patrish and Wozzle for all the information you have supplied me. I,m not sure if the 1841 census info is correct,but as there is no other alternative, I will keep it in mind, as for the info from Wozzle it looks to be the John Threadwell that I am looking for, I have noticed on the 1851 census, John gives his occupation as "boiler maker", not sure what his occupation is on the 1861 census though. I will try to digest all of this and apply to the records I have already got and get back to you.
Once again I thank you both very much.
