Hi Helen. I was able to find my doctor in the book:: 18th century medics:: that I got on library exchange. I was able to find reference to him 1783 and 1789 in Fowey Cornwall but I still have no idea where he was from. He died in Swanage Dorset 1821 aged 68 and I found lots of other news of him at that town,but as of now I still am stuck like yourselfb . Lots of luck.Brian. Brian DAVIS concord CA USA
