Same here. Seventeen of the 25 barons had progeny and I am related to 14 of them. I know that Richard de Clare takes you straight to Charlemagne, and ultimately, Adam. Joseph of Arimathea was also in that lineage.
Because I’ve got Plantagenets I’ve got William duke of Normandy, and because I’ve got William I’ve got Charlemagne. Oddly, I’m as proud of Charlemagne’s grandfather Charles Martel as I am of Charlemagne.
By the way, that makes you cousin to George Washington (and a slew of other founders).
