Oh dear lord. but wait, there's more!
https://www.sothebys.com/en/buy/auction/2022/the-william-k-du-pont-collection-important-americana-from-rocky-hill/exceptional-carved-and-figured-maple-engravedNow, in order to complete the twisting of reality whereupon an earlier rifle signed "John Rupp" can be attributed to a man named George, we next proceed to come up with a mutated description of a rifle clearly of the 19th century and attributed to John Rupp II, and attribute this rifle to John the elder because otherwise the desired narrative falls apart even further! Nevermind John the elder did not die during their noted death date of 1836 (demonstrably proven false by the words of his own brother Herman), nor did John II work in Weisenberg township (he was in Macungie as I proved with census records) and in fact there was no John Rupp in Weisenberg until the taking of the 1850 census, at which point he was 8 years old and the son of Solomon Rupp.
Even more obscene is the absolute carelessness with which they use the alleged birth/death dates of John Rupp the elder, 1762-1836, and then in the next sentence describe him as "son of Andrew" who was the brother of that particular John Rupp. A son and a brother all in one shot - what are they saying about this poor family?
Regardless of what Sotheby's is doing with these insane descriptions, what is even more ridiculous is that they are apparently relying upon "experts" who are not undertaking original, documentable research, but rather are simply running right to the 'county histories' to rehash non-documented, garbled information and subsequently presenting it as fact.
What is most frustrating is that here I am, up on a mountain in the middle of the woods near the NY state line, dealing with internet that is not much faster than dial-up and looking at a 2+ hour drive one-way to visit any of the downstate historical societies or record repositories, and meanwhile, a number of these "experts" live IN THE FREAKING AREA and can't be bothered to do anything more than open a "county history" book.
I better go split some more firewood right now.
