The Genetic Genealogists of Red Earth Genetic Genealogy

Based in Oklahoma, Red Earth genetic genealogists have been trained under some of the best in the field. We have worked a number of high profile solves involving both Unidentified Human Remains and Crime Scene perpetrator identification. Pioneers in the technique of Medical Inherited Genetic Genealogy, we are helping set the standard for this emerging work. We also have completed dozens of unknown parentage cases for individuals over the past several years. 

At Red Earth Genetic Genealogy, we place high priority on ethics in the field and operate under the highest legal and privacy standards. We firmly believe the future of this practice depends on it.
