Here's the funny side to this tale. . .
In the Pagan/Wiccan world of today you will find spurs of a rather antiquated family line (actually, there are several family names associated with it these days) that supposedly goes well into the Ancient days of Egypt, Babylon, etc. with the radical King Akhenaten (kind of ironic given that he was a monotheist, but hey...) Their claim is "royal blood" or to be more specific, descendency from the "Gods" (a.k.a. aliens -- the one's that came here, subjigated the still evolving human race, using the more intelligent/evolved as a DNA source for creating a hybrid that would allow their race & culture to survive. . . understand, most of these aliens started off in Atlantis or Lemuria then migrated to Egypt, the Orient and parts of Northern Europe as the continents sank . . )
Nonetheless, the long running list of genetic "proof" to those belonging to said bloodlines has been amended so as to include rare blood factors as well as types. Any person hosting more than 3 of these traits qualifies as being worthy to wear royal Purple in the lining of their ceremonial robes as well as access to the "deeper mysteries" (see:
Mastering Witchcraft by Paul Huson)
The real irony comes when we look at texts such as the Malleus Maleficarum where we find most all of the physical traits echoed (clue that an insider was forced to spill their guts. . . literally
), if it were to be contemporary I'm certain this blood factor would be included
BTW. . . not only was my ex part of this particular tradition, I likewise qualify and have several distant relatives seriously vested in this legacy as well. I can't honestly sustain the claims of antiquity for several reasons, the least of which is the use of Budge's interpretation of Egyptian writing vs. the latter formulated methods that render far more accurate understanding.
