O'Donnell Surname Project- Background
All Variants, Ó Dómhnaill, ODonel, ODonell, O'Donell, ODonnal, ODonnell, O'Donnell
While a surname itself may give us incomplete or misleading or, at best, only general information about the origin of a family, DNA-testing can give us concrete evidence for identifying and separating family lines. Y-chromosome DNA testing is especially helpful because the male Y-chromosome is handed down, father to son, unchanged through the generations, except for rare mutations which, in themselves, can be helpful indicators of branching. The accessibility and affordability of family DNA testing is doubtless the greatest technical advance in the history of genealogical research because -- at long, long last -- we have a tool to break down those brick walls!
mtDNA testers! WOMEN who have O'Donnell's in their genealogical family tree are WELCOME to this group! You may upload your family tree mtDNA data with GEDCOM family tree genealogical data, showing all surnames including O'Donnell surnames. Your membership grants your access to those with whom you may find kinship.

Scientific research and yDNA testing has moved us on from our early beginnings not that long ago.
