Thank you so much, Phil and Janis, for your response.
The likeness is almost spot on; date of birth, name, occupation, and living place. I so wanted it to be true.
The town in the west-coast of sweden from where he was the church burned down with all the books of records, which make it hopeless to find any roots on this side of my family-tree.
If my great grandfather write in his book about a visit from a ageing sea captain Johan Andersson, the time would be 1889-1890 and that would rule out this John Anderson settled in Stockton. And you, Phil, find the death records to be of 1862, which unfortunately halted my hopes.
I truly appriciate your reply. Thomas
