"Pastor Croll was an accomplished historian and obviously made use of the best available sources for his text...he discovered, in the Historical Society of Pennsylvania,...the first history of Oley, the lengthy manuscript entitled 'Fragment of the past history of Oley', by Dr. Peter G. Bertolet...This was based largely on interviews with Oley Valley residents, many of whom were born in the 18th century....After several competent historical chapters on the settlement and early religious patterns and conflicts in the Valley, Pastor Croll concentrates on some of the major families of Oley."
