I did the National Geographic DNA test - which is a "remote ancestry" test. Basically I found out that my X chromosome is fairly rare and is most common in Poland (and uncommon there). Also that I have about half the "usual" amount of Neanderthal DNA. I did the Ancestry DNA test because I have been a member of that website for quite a few years. The result that I have ancestors from nearly all of Europe was not a surprise, but that I am supposedly 31 % Irish was. I am almost exactly 1/8th Scandinavian, which makes sense because one of my great grandfathers came from Sweden. What I didn't expect was that supposedly I am 6 % Italian/Greek. But there is a family tradition that my while my Rippetoe line came to America from France, the family was ultimately of Italian origin. Also it is possilbe that my German DeFroehn line was orginially from the village of Frain in eastern France. The one very good result of the Ancestry test, is that it is now proven that Miles Mark was a son of William Mark. This had been a matter of debate/dispute for at least 30 years. So far the Ancestry DNA test has not helped with any of my "brick walls": Eggleston, Mark or Purnell lines. It has been claimed that the Eggleston family is the most researched family in America, except for my part of the family! The three surviving children of William Mark gave the following on the 1880 federal census as the birthplace of their father: England, Connecticut and New York! Several different Purnell families immigrated to Virginia, Maryland and Pennsylvania in colonial times.
