Hi Mandrake,
If you send Anthony a PM he should be able to check the 1865 and 1870 directories for you.
James Tedford's going well. The 1880 directory on the Lennon Wylie site shows that he's moved house again and the business address has also changed. I'm not certain if he was a provisioner and making sails as the alphabetical section of the directory doesn't mention that matter.
Tedford, James, ship chandler and nail maker, 5 Donegall Quay, res., The Mount, Mountpottinger
