Yes Joanne, that's him.  What I was doing was offering to share the research I had done on him with anyone who might be interested.  I had to do it because my ancestor is also Joseph Double, also born 1809, also in Raydon and I needed to be able to distinguish between the two.  (As it happens, my Joseph was also transported, in 1840, but to Bermuda - lawless lot these early Doubles).
