Not that long ago (9-23-2014), I got the answers to questions I had about my family history and as an added bonus--through the DNA test--I was able to discover other relatives online.
I will tell you that parents might want to consider purchasing the kit, if not for yourself, but for your children. Even though we live in a large world, it is small too. Nowadays, people are able to connect with half sisters, brothers, cousins etc. online via dating websites very easily. Just think, one's son or daughter comes up to you one day talking about how compatible he or she is with someone only to find out that they have a white, black or another ethnicity for a cousin.
So do consider taking the time out to get your Ancestry DNA done. By the way I found out that my ancestors came from the Congo/Cameroon, Nigeria, Ivory Coast, Benin/Togo, West Europe (Iberian Pennisula, Ireland...), Native American, and Polynesia.
