I cannot tell from your query if this is the same individual, but I have in my database a Jesse Pennypacker who died at Charlestown, Chester Co., Pa. on 6 July 1838. His wife was Rebecca Little (22 Sept. 1803-7 Aug 1869). They had three sons of whom I have record: John, Joseph, and George. Of these sons, Joseph (b. 1836), died in Denver,Colorado,11 Oct. 1875. The other two men stayed in Pennsylvania. John lived in Philadelphia and sold agricultural machinery. George was a farmer in Charlestown. Both men were still living in 1877.
