I had a look at the 1861 Census by address and a Joseph Jackson is not listed as living in Wilderness Row. I think I found him, searching by name at 21 St John street, Clerkenwell.
He is listed as a lodger, b1831 Middlesex and occupation pencil maker (it has been transcribed as pensie maker but checking the image, it looks more like pencil).
