Have you already had your DNA tested?
If you have already gotten your Y-DNA tested by Relative Genetics, Sorenson Molecular Genealogy Foundation, Ancestry.com, Oxford Ancestors, DNA Heritage, or one of the other DNA testing companies, you can join this project by sending your Y-DNA test results and Grau pedigree to this project's administrator.
When you join the Grau DNA Project, your yDNA and Grau pedigree will be analyzed for free to determine whether or not you fit into a Grau family group already established through Y-DNA analysis. It is also possible that you will match one of the Grau singletons who have not yet found a Grau match, thereby establishing a new Grau family group.
