Family Groups Y-Lineage
We list all pedigrees for those who wish to be listed. We also post DNA results and pedigrees obtained from other online public databases. If you recognize your DNA results or pedigree and wish to have them removed, let us know. We hope that all Grau families will eventually be listed on these pages. We also hope to ultimately locate male descendants of every Grau family to arrange for their DNA testing. Participation in the DNA Project is not a requirement for listing on these pages, but we strongly encourage DNA testing.
