Our Daughter has traced mine and my Husbands families. She has gotten me pictures I would never have if not for her connecting with one of my distant cousin. I remembered names I had heard most of my childhood and that helped. My Husband and I did the DNA. I found my Mom was not right, she had told my late youngest Brother and I different things we were suppose to be. Years after she gave up ancestry membership one of my cousins on my Dad side contacted her. Some of the men on his side were not very nice men.
Since my parents and siblings are dead I had no one but my kids to share the findings with. It wasn't important to me but the Daughter cared about it. I am not worried about usage of our DNA results.
