Hi, everyone.
There were two Charles Kempers who lived in Virginia at the time of the Revolutionary War, and both participated in it. The old Kemper Genealogy, the records of the Germanna foundation, and the records of the Daughters of the American Revolution all support this. In fact, according to the Germanna Foundation, these two Charles Kempers were relatives.
Charles #1 (b. 1756 & d. 1841, DAR #A064509) served with Turner, Edmonds, et al, during the war. His wife was Susanna Mauzy, his father was Peter (John Peter Kemper, called Peter not John), and was buried in Culpepper in the old Kemper family cemetery. According to all the records I mentioned earlier, this Charles did not have a son named William.
Charles #2 (b. abt. 1753 & d. aft. 1787, DAR #A064507) was a private in the Fauquier County Militia during the Revolutionary War, serving with Capt. John Ball. His parents were John (or John George) Kemper II and Ann Weaver. Charles' father John provided supplies to the troops, and his contribution did qualify him to become a DAR patriot ancestor (DAR #A064521). The maternal grandparents of Charles #2 were Tillman Weaver and Ann Elizabeth Cuntze. Grandma Ann provided hay to the troops, and her service qualified her to become a DAR Patriot in her own right (DAR # A123137). Charles #2 did have a son name William, who in turn had a son named Reuben Allen Kemper, who in turn had a son named George Allen Kemper, who then had my grandfather Willie Nay Kemper.
I will post more as I find more. I hope to find some original source material when I visit Germanna, but it may take a few months to get there.
