Re: Singers of Pennsylvania
Based on the will of Jacob of Derry who died in 1800- he is son of Johannes Zenger d. 1790 and Barbara. (not Simon and Elizabeth- their Jacob moved with rest of family after his father Simon died in 1763 to Carslile Pa)
The will of Jacob of Derry has Conrad Singer signing as a witness. This supports the theory that Jacob is brother of Conrad and therefore son of Johannes Zenger (John Zinger/Singer). Jacob's land is very close to land of Johnnes Zenger. There has always been some confusion about who this Jacob of Derry died 1800 belonged to since both Simon and Johannes had sons named Jacob. I believe his will clears this up.
