The Corson DNA Project is mainly a Y-DNA Surname project established in July 2004. It began by targeting descendants of the largest known families to determine if family progenitors (men born in the 17th or 18th centuries) were related to one another. Some project participants have taken autosomal DNA tests.
- To determine relatedness among descendants of known family progenitors, as well as relatedness, if any, among the progenitors themselves.
- To determine the geocultural origins of these progenitors as precisely as possible.
- To connect individuals unsure of their male-line ancestry to a particular family.
- To deduce whether "brick-wall" ancestors are related to each other or to known progenitors (and if so, how).
At least a dozen Corson (and variant) family lines are known, of which eight have large numbers of descendants in North America, the United Kingdom, and France. For more information, visit Known Lines and Their Origins
- The progenitors of the major family lines are not related to each other (in the direct male line) in a genealogical time frame. A summary of STR and SNP results for each family line is provided here.
