After the Flood - by Bill Cooper
Europe traced back to Noah"
The following genealogy shows the descent of the early British kings as it was traced down from Japheth, the son of Noah. The sources for this are Nennius 17 and 18 (see Appendix 5), covering from Japheth to Brutus; and Geoffrey of Monmouth who carries the story on from Anchises. To gain an idea of the time-scale involved, I have included the dates of each king's first year of reign as far as that can be calculated from internal and external sources. The Welsh chronicle agrees with Geoffrey of Monmouth almost exactly, although the names are obviously closer in the Welsh to the original early British forms than they are in Geoffrey. For ease, I have used here Geoffrey's latinised forms.
