Our extended family is searching for definitive information regarding the Lycoming Co. history of John Irwin and his family. The census records of Washington Twp. back to 1820 refer to a John Irwin, but then two John Irwin's (father and son?) in 1830. There are also other Irwin's and Ervin's associated in the township in the various census records, including 1840 that identifies Peter Irwin (my g g grandfather). There is a true mystery of persons here as we are getting mixed records to this Irwin family before John N Irwin and Susan Bailey (sis. to Jacob Bailey of Elimsport).
Is someone available with resources on any further written record in the county on the origins of the family and their life in Lycoming County?
