My mom located a half sister through 23 and me. My grandmother had made a deathbed confession about an out of wedlock pregnancy in her early 20s, several years before meeting my grandfather. Seems she was working at a Naval yard during WW2. Quite the scandal... she was sent away to have the baby, which ended up in a fully closed adoption. No info, no names, no contact for 70+ years. Till the DNA match popped up. We all met her a few years ago... She was the spitting image of my grandmother. Her biggest questions to us were just general information and family medical history. It was quite an interesting experience...
