Dear Jane,
I am sorry no one has responded to your request. Maybe others are confused, as I am. Can you clarify a few things about Thomas? Was his middle name Duckworth and his surname DAWSON? Is there a profile for him on WikiTree that you could link here? Where is the (town?) of Bradford to which you refer? This information could help others be sure that they are working on the same man.
Good luck! -NGP
