The book "A history of Vaughan township" by G.E. Reaman has a lot of information about the Puterbaugh of Vaughan. It has a great index and the name Puterbaugh is in it quite a bit.
G.E. Reaman also wrote an amazing book "Trail of the Black Walnut" where he details the journey of the various Pennsylvania Dutch families to Ontario, including Vaughan Township. G.E.Reaman was himself of Pennsylvania Dutch descent and related to most of the Vaughan families.
Both books are available from many libraries with decent genealogical collections or by Interlibrary loan.
