I am trying to confirm information regarding my 4G-grandfather Peter Shipe (or Johan Peter Scheib). He was born 1738, died 1823, married Elizabeth Walker (Welker). The following is from TN Historical Marker 1E60 at US11W and Shipe Road in Knox Co., TN: "Peter Shipe born 1738. He lived near Natural Bridge, VA, until enlisting in the Revolutionary War. He served later as baggagemast to George Washington. . ." Any help will be appreciated.
