The Y-chromosome continues through the next generations as shown to the right. Starting with Enddolan (Js-2) at the top of the figure, the next six generations are shown down to Vortiger (Jm-1) [Gwrtheyrn in the Welsh]. From the first generation known, Manogan (Jw-1), to Vortiger (Jm-1), there is a total of 16 generations. This group of Y-chromosomes would roughly represent 450 years, defining approximately 41 years per generation. [450/11]. This would be the time of Roman occupation. [Roughly 50 B.C. to 400 A.D.] Much more to come.
