It’s a step everyone should consider cautiously. Considering surnames are a relatively recent convention and at that the oral history passed down of such can be an extremely “malleable” identifier, DNA testing can significantly unravel some aspects of both maternal and fraternal lines. Whether one is open having that knowledge and all that it may reveal is probably the most important question to ask oneself before venturing. However it contains a wealth of information. Just considering family names, from ourselves to our grandparent we have contributions from possibly 8 different family names and it goes exponentially onward. The cautionary note, as previously posted, is the question of how that information can be used and misused.

Some of the companies are more free with your information, but there are those who guard it cautiously. Buyer research!

As a bone marrow donor, my DNA is out there.
As former military my DNA is out there.
So for me it was an easy leap. I chose the most restrictive company I could find, but there are no guarantees against security beaches i suppose. I found it fascinating and continue to get useful information It certainly has slowly peeled back some of histories fog.
