Not scary, no. The two best things that came out of it were these. I always knew my great-great-grandfather had a brother; I found one of the brother's descendants, and she had our line back two generations. On another line, I met Bill, who knew almost nothing about his heritage. I was able to share a photograph of his great-great-grandmother with him, as well as other family stuff which he would never have known about if we hadn't met through DNA. But in most cases, I wonder why people got tested since they don't respond. But email is tricky. Maybe they just want to know their ethnicity. Who knows?
