My Grandfather was adopted, but we have birth certificate so we had the family name. Did the DNA out to 37 markers, but had no real strong matches within the family name/DNA. Got an email about 6 mo later from someone researching his family tree (another family name), turns out I'm a match to his ancestor. If you trace back several generations, our ancestors were in the same towns in NE and had members of both families married to each other.
Must have been something going on
