  == Number of Túatha? == Does anybody have any knowledge of how many túatha there were in Ireland? Obviously it was constantly changing, but does anyone know the average number through the period they existed? I remember hearing from school that there was about 100 túatha in Ireland in the middle ages. And if, as this article says, a Túath had about 10,000 people that would mean about 1 million on the whole island, which sounds about right from what I've heard of population estimates of the time. So should I just add in the 100 figure, as I do distinctly remember being told that number in school?
