I am new to this web site. I seen your inquiry for info on Isaac Shimer and Sarah A. Delashmutt. I am a decendant of Jacob and Elizabeth Scheimer. I have an Isaac Shimer born in 1765 Hanover County, Pa. died July 9,1845 in Marion County, Ind. His wife is Sarah A. Delashmutt born Jan.31, 1773 died March 28,1856 Isaac and Sarah married Jan. 16, 1798 in Maryland. I have them as having two sons. Jesse Shimer and Elias Nelson Shimer. Found this info in the Shimer's of America book. I do not know if this Isaac is the same as your Isaac. But just thought that maybe... by chance it is.
