I guess this is somewhat odd, but I don't have the slightest difficulty believing that Julius Caesar is the direct blood descendant of the Greek goddess, Venus.
My faith tells me that every person of any Germanic descent is of direct blood relation to the Aesir and Vanir-- and that's a lot more people than any White Supremacist group will ever admit to, with migration patterns, trade, and people going a-Viking.
Most pantheistic faiths give the race of humanity descent from their gods, and in many cases, a closer, more direct bloodline, when the gods get frisky. In particular, I know the Greek and Japanese old faiths believed in divine lineage.
Given those tendencies, I suspect that far, far more people on this planet have some form of divine lineage than anyone would believe.
On a more mundane note, I'm the fourth or fifth cousin of New York Yankee Lou Gehrig, and roughly eighth- or ninth-removed grandnephew of the fourteenth American President, Franklin Pierce.
