I looked that up and was surprised to find the entire lineage actually goes back to the first traces of the formation of the Monarchy, to William I (The Conqueror) and even to some of the warring pretenders to the throne beforehand...pretty fascinating and surprising - I thought that throughout history the throne had probably been taken by different powers at war coming in and taking over...but all of the squabbles over the throne were actually inter-family when they took place...not always immediate family, but still family. Just a brief interruption by Cromwell to their continuous reign.
well, the Royals officially trace their lineage to the kings of Wessex..., 400 years before Willie
well, most of the royal families of Europe are related to each other -- you know that the King of England, the Tsar of Russia and the Kaiser of Germany in WWI were all first cousins? All had the same grandma -- Queen Victoria?
And memebers of the Saxe-Coburg-Gotha's (the real name of the Windsor family) include Kings of Bulgaria etc.?
