Speculative Haplogrouping of Untested Dynasties. Based on the royal test results available, the overall Y-DNA results from Europe, and the geographical convergence of many of these lineages on Denmark and Germany, it is hypothesized that the Normandy, Wessex, and Knýtlinga dynasties will be found to come from the R1b-U106 haplogroup. The Tudor line is likely to resemble the Stuart line and come from haplogroup R1b-L21. The Plantagenets are a bit more difficult to predict as some speculate that they are related to the Carpetian kings of France and descended from Roman citizens in the haplogroup J2 or G2. However, early sources attribute them as Germanic Franks13 and thus more likely to be another branch of R1b-U106.
Let them come who wish to come, And let them go who wish to go, And do not harm to me or mine. -Ancient Icelandic Invitation Formula for the Elven Folk
