The Sellen DNA Project welcomes all participants. We encourage you to join today!. Our project is just getting started, and we expect to have many exciting discoveries. Participating is an opportunity to uncover information not provided in the paper records, which will help with your research of your family tree. We will also discover which family trees are related. As the project progresses, the results for the various family trees will provide information on the evolution of the surname. The surnames in this DNA Project are researched as part of the Sellen one-name study . You can learn more about this significant research, and the the associated family trees, by contacting the Project Administrator. Sellen@one-name.org The Y DNA test tells you about your direct male line, which would be your father, his father, and back in time. You must be male to take this test, and you should have one of the surnames shown. If you believe there is a Sellen or variant in your direct male line, although you have a different surname, you are also welcome to participate. If you are female, you will need to find a direct line male in your family tree to participate and represent your tree. We encourage males who order a Y DNA test to order 37 markers, if possible. If you order less markers, you can upgrade later, though this costs a little more. Both males and females may also be interested in learning about their direct female line, which would be their mother, their mother's mother, and back in time. Both men and women inherit mtDNA, although only women pass it on. You would order a mtDNA test. For matches in a genealogical time frame, order the mtDNA Plus test.
