The Hollyer DNA Project welcomes all participants. We encourage you to join today!. Our project is still in the early stages, 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 also researched as part of the Hollyer One-Name Study, including Hollier and Holyer. This significant research and information about the surnames and the associated family trees can be found at: http://www.hollyer.name 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 Hollyer or variant in your direct male line, although you have a different surname, you are also welcome to participate. We are also accepting those with the surnames Hallier or Ollier, as there is some potential or actual crossover between these names. If you are female, please find a male to participate. We encourage males who order a Y DNA test to order 37 markers, if possible, as this may give the more information about specific branches. 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. You would order a mtDNA test.
