Pettigrew & Oulton directory of 1840 shows him at 7 Shaw St. in the city centre as an agent.

page 60 (left hand side of the image, about half-way up)
and he's listed in the 1834 edition at 18 Dame St. as a 'Hosier & Glover to his majesty & the Lord Lieutenant'

page 21 (bottom right of the image)
His occupation in the 1834 listing could tie in with the occupation listed for that William Rogerson on the 1851 census in London - i.e. 'Elastic Fabric Merchant'
