O'Donovan Clan YDNA - mtDNA Test Results for Members

The table below shows each project member's kit number and their tested mitochondrial DNA (mtDNA) results. According to the project's settings, it may also display the earliest known ancestor of each project member. Following scientific standards, FamilyTreeDNA compares all mtDNA results to the RSRS. The earliest known common maternal ancestor to all people alive today as well as several ancient humanoids are the basis for the RSRS. Thus, a comparison to this reference reveals clearly the path between each person and our shared maternal ancestor. In general, those who share the same direct maternal ancestor within the last fifteen generations should have mtDNA results that match exactly.
