Through a DNA match, I discovered a 1st cousin; who'd been adopted at birth and didn't know that my uncle was his father. My uncle had met his mother just before he shipped out to Europe in WW2. He was seriously wounded and never found out about his son. I was able to help him identify his father and then shared stories, pictures, and information about his half siblings. Then through another DNA match, I discovered a 1st cousin once removed. She had been adopted at birth and only knew where she was born. I helped her find her father, who is my first cousin; he took a DNA test and confirmed their relationship.
