Pretty sure it was a hoax. Only thing we know is that story-wise the Belmonts passed the Holy Whip to the Morris' sometime during the 19th century, although it's still unknown whether it was actually Richiter or his heir (now that I think about it, Richiter was the last Belmont to wield it, we just have no idea who his heir was). This is the "grey area" of the timeline, which has yet to be filled with the finer details (other than Quincy defeating Dracula in 1897, obviously after Shanoa which I guesstimate to have been 30-50 years prior [OoE intentionally doesn't specify an exact year])
CotM should be and is viewed as a "stand-alone" game, separate from the canon timeline; the developers most likely intended to make a prequel game at one point due to certain elements in the story, but, y'know, things change.
