John O'Brien's compilation cited by Jan, "A Listing of all Known Warren County Cemeteries," within the Warren County Cultural & Heritage Commission web site, states that in addition to the Wiggins burial mentioned by Jan there was an unnamed abandoned cemetery in Vienna, with "Inscription records" at Snell's _History of Sussex And Warren Counties, New Jersey_ (1881), p. 739. This _History_ states that "there is no trace left" of this cemetery. Oh, well . . . Judy
