The Families of today The descendants that are alive today are living throughout many different countries. As many as 3 million people in the world can trace their ancestry back to King Naill. Which means I have a very large family. This is all due to him having up to as many as 12 children. The family spreads across the world in places like Austrilia, Spain, Canada, United States and many others. There are actually more Irish people living outside of Ireland than in Ireland it's self.
