I agree as you go back 10 generations you have over 1000 ancestors, 20 generations 1 million etc and if Niall existed as such we would be a descendant of his. However, I was laulled to glory thinking that he was my direct paternal Y DNA ancestor and that's where it all falls apart especially with a certain company from Houston with a Niall banner across my page and sinking beaucoup bucks for that glory. However, when studying the texts and ledgers it becomes quite clear this Niall never was what he was supposed to be. Now I believe Niall was a minor player in Irish history and never was a high king of Ireland crowned at the Hill of Tara. In fact, our M222 certainly has more famous ancestors to discover than the Niall tale and lets get off this fictious Niall kick.
