I'm seaching for my bio great grandfather. I have name, birth year, occupation and where he lived in Norway but have not been able to find him. Several people have directed me to a Swedish person with the same name, birth year and occupation in the same area, but I was not convinced. This person had his own family and died just 3 years after my grandfather's birth. Anyway, I managed to find a man who is the grandchild of this suspected man's brother and he agreed to take a DNA-test. IF it was the right/same man, the man who tested would be my father's 2nd cousin. They did not match (at all). The tested person however had a grandchild to the suspected father as a match which really confirms there is no connection at all between our families.
How would you write this in the bio? I tried in research notes in of my great grandfather, but if feels very confused when I read it (also when I try to explain to you above). Anyone care to check it out and come with suggestions how to formulate it as clear as can be?
