Family Tree DNA Company does not have a Yerby DNA Project at present. If any male Yerby wants to try the DNA test to establish and document his line of Yerby's, please join the Yarbrough DNA Project to receive a discount on the test. After two or more Yerby's are tested, then one can establish their own "Yerby DNA Project" and unseubscribe from the Yarbrough DNA Project.
DNA testing can untangle the various Yerby lineages. All who take a DNA test must be prepared to discover tht their original surname line may not be Yerby due to a non-parental event - many such occurances happend during the various wars in the USA.
