A 2003 study discovered through DNA analysis that as many as 8 percent of the male inhabitants of Asia are probable descendants of Genghis Khan, the Mongol warrior emperor, leader of the Golden Horde, and founder of an Empire that stretched from Central Asia all the way to gates of Vienna. However due to his even more considerable conquests with the opposite sex, it is estimated that Ghengis Khan has roughly 16 million male descendants -- i.e. half of one percent of the entire male population of the world.
What has this got to do with Ynys Môn? Well, take a look at this inscription from a tombstone at Eglwys Tregaian, near Capel Coch:
William Ap Howel may not have conquered half of Eurasia, but I wonder how many of us Islanders are descendants of this clearly extraordinary man?
