My husband and I decided to go with 23andme after talking with a friend who discovered her birth mother in Australia through DNA. Mine was curiosity, I have been researching my family tree for years. Nothing new came from my DNA but I get new relatives every month. My husband never knew his father so I had spent thirty years looking for him. I finally found family and was in touch, but we could not be 100% sure. When his test results came back he matched with another family member. I was elated that all my research had produced results. This was very important to me for health reasons, genetics play a part.
