The most likely person would be Johann Phillip Klahr (Johan Jakob's son). He was rich. He owned TONS of property. He left 1300 pounds to each of his 15 kids when he died. If you want to know more, look for a book called "johan jacob klahr" by Rex O. Matthews. He's done a lot of research on the klahr line. If your close enough, you should visit the berks county genealogical society in the goggle works in reading. There's 6 huge binders of klahr stuff on the shelf in front of the computers. Most of it was from Rex i think. It even has letters between him and a klahr descendant who still lives in germany.
