Who Was The Wampyr?

In his book The Highgate Vampire, Seán Manchester states that the vampiric source of the Highgate infestation first showed up shortly after the infamous vampire plague of the early 1700's, the same era as Arnold Paole and Peter Plogojowitz. He further states that an Eastern European nobleman rented Ashurst House in the early 18th century. This all seems to make sense, and it suggests that Tamás Orszag of Hungary is the most likely candidate for the identity of the Highgate Vampire.

But this is by no means certain.
