Re: trying to see if its possible to extend a family link in the Harrison Family
Barry,
This may be of no use to you at all but I have a Harrison/ Robinson connection with the Robinsons being in Sheffield back to about 1800 (I am also stuck there) but my Harrisons were from the Doncaster area and worked on the river. That is Richard Harrison was a "mariner" born in 1763. Both his granddaughters, Hannah and sarah (Sally) Lodge were born in Doncaster and married Robinsons in Sheffield in 1836 and 1844.
Richard had at least one brother William born in 1760 but I have no information on him or any other siblings.
I know this is a bit early for your man however it might be worth looking at this family. They are on Find My past.
