My dad got his DNA scanned and forwarded the results to me and my brother.
After he got his results, he heard from a relative, George Crawford, who tracked him down via the service.
My dad says, "After my DNA results I received an email from a DNA match who turned out to be a grandson of Grandpa Crawford's youngest brother. Thought you might be interested in his emails. -jerry"
He forwarded this thread of emails intoducting himself and sharing his knowldege of the family tree. Apparently George is really into geneology.
