In one of my books, "This Was Prince William" by R. Jackson Ratcliffe, 1978, there is a photograph of the tombstone of this man. All that is visible in the photograph is a cross with the name Peter Wagener, Colonel, VA. Troops, Rev. War. The author states "Peter Wagener, who was buried in Fairfax County near U.S. No. 1 and near Occoquan Creek on the lands of the present Lazy Susan Inn, was the second Clerk of Prince William (1742-1752), although he lived in Fairfax. By an arrangement with John Graham, who was Clerk of Fairfax but who lived in Prince William, the clerkship was exchanged and Graham became clerk in Prince William and Wagener became clerk in Fairfax."
