Anyway, the whole blood curse that goes back centuries is a common motif with Bob Larson's exorcisms because it's super-easy for him to lay the blame for your "possession" on some anonymous ancestor who probably never existed and, even if they're naming an ancestor they're aware of, they've been dead a very long time and can't defend themselves.
But I submitted this one in particular because the idea that there were Freemasons doing blood rituals many centuries before the generally accepted origins of Freemasonry is just ludicrous even by Bob Larson ludicriousity standards. Even if I assume the average generation is 15 years instead of the 20 year calculation I made in the description, it'd still be, like, around 1050 years ago.
