"Numerous cemeteries were relocation during the construction of Kinzua Dam and Allegheny Reservoir in the early 1960s by the U.S. Army Corps of Engineers, Pittsburgh District.
Remains in Kinzua Cemetery, which contained approximately 1,336 graves, and Morrison Run Cemetery, which contained approximately 62 graves (another record said 89), were relocated to Willow Dale Cemetery in Bradford, Pennsylvania. According to Pittsburgh District records, 1467 remains were removed from both cemeteries. "Reinternments of 40 of the remains was made in alternative cemeteries" (Those alternative cemeteries were not identified.)"
Perhaps this will give you a lead?
