Johan Helfer Cramer (NSDAR #A067412)served with Capt. McDonnell's unit during the Revolutionary War. He married Sophia Neudig on 5 Apr 1785. His grave has been marked by the DAR. For additional information this Cramer line, see "The Cramers in America" by Clarence Cramer. Clarence hired a York Co. Genealogist to document the family tree and gave the result as a Christmas present to the Cramer cousins in 1943. To my knowledge, copies can be found at the York County PA Historical Society; Kaubisch Memorial Library, Fostoria, Ohio and the Daughters of the American Revolution Library in DC.
