Joseph Cooper.

From the census, Joseph appears to have been born around 1810.

Someone on the familysearch site has submitted the following details :

Joseph Cooper born 18 Jun 1809 christened 15 Oct 1809 Over Darwen, Blackburn
father Richard Cooper mother Betty

No church has been given, as there are dates given it is a case of trying to find the appropriate parish records.

The batch no. of this information is 7425305 and you can see what other information they have submitted including Richard Cooper about 1770 of Darwen and Betty Duxbury (married) about 1789 Darwen. As no dates are given this has to be viewed as a guess !!!

This can be linked to an entry on the IGI. (also on the familysearch site) batch no C133071 Over Darwen Lower Chapel Independent christenings 1751-1837

Benjamin Cooper christened 28 Jun 1789 born 11 Jun 1789 parents Richard Cooper and Betty Duxbury

It would appear that Benjamin may have been Josephs older brother but this has to be viewed with much sceptism until further proof has been found. Benjamin's christening though does tell us that we will have to look at nonconformist churches. We need to find Joseph's and look at the original baptism record of Benjamin, and find Richard and Betty's marriage. Also the fact that Joseph does not have a son called Benjamin also goes against there being a connection.

From other information (which I shall post later) Joseph definately had a sibling and at a guess we are looking for a brother James.
