The British used men who had been captured by the indians and returned to Col Bouquet as spies and go betweens with the Indian communities. This happened with my ancestors the HICKS ( GRESHOM, LEVI, MOSES) who had been taken as boys from the Canoe Valley and lived with the Indians for 10 years. After they returned they continued to wear Indian clothing etc and were used by both the Army and the Church, never really totally trusted! Lyman Draper did a lot of interviews with Revolutionary Soldiers and their children, perhaps the information you are looking for is there. Available at most FHC. Unfortunately he never put it into Manuscript form and so there are just a series of Papers. The Brady and Weitzel series are very good (certainly they are heros of mine), during the period after the Revolution ( the Shawnee uprisings) But I do not remember reading a lot about organized Ranger Units in Western Pa during the Revolution, or afterwards when it was so dangerous on the Frontier, will try and interlibrary loan your suggestions. Thanks Was Samuel Piersol related to the Piersol family from Chester and Berks Counties who had a history of dealing with the Indians as Traders?..I have Piersols from there..happy to exchange. Ris
