Recently, we were informed of a company that was providing information based on DNA regarding ancestry. This has apparently become more popular with the many technological advances, making it pretty affordable. They send you a kit, you supply the DNA (typically saliva) and they run the DNA in their labs. The information you receive regarding ancestry includes global similarity, relative finders, and DNA (haplogroup) matches. In addition to ancestry information, the DNA test also provides health information such as disease risk, drug response and traits.
I recommend doing your own research to see if this is a good option for you regarding your own family searching. It can provide information that you would not receive otherwise and can be very insightful. It also allows you to connect with others who have taken the tests who have matches to your haplogroup.
