Appleby, that's good information and has cleared up the puzzle re this Samuel Cammish who, from the info you have kindly given me, worked in Quay Street till the 1950's, and now I know that the man with an American wife was nothing to do with my family, which was really confusing me.
So now I must do some tracing back to try to find out what relation the Samuel Cammish (who worked in the tin smith's till the 1950's) was to my Great Grandfather Samuel, (d.o.b. 1850) I am now wondering if he was a grandson.
I've managed to trace back to a great, great, great Grandmother Ann Cammish, born in 1791 and her seven children, fishermen and shoemakers seems to have been some of the family trades, and of course tin smiths. I'm related to the Scarborough Cammish families and have gone back five generations so far. It's so interesting........but time consuming!
Thanks again for taking the time to explain re Bob Goodall and his American wife, I think the person who told me they were one and the same had sort of merged the two characters together over the years!
