It's the same township, with the same name in pretty much the same place it's been since it was created. It's the counties that have changed and may be what's got you stumped. Prior to 1815, Derry Township was part of Northumberland County. At that time, Columbia County was formed from Northumberland and Derry became part of it. Later, 1850ish, Montour was formed from Columbia and Derry, once again, was part of the portion broken off into the new county. Washingtonville is its main town and, I believe, only borough; one of two in Montour County. To confuse you a little more, before Northumberland, the area would have been Lancaster County. General settlement of this area began around the close of the American Revolution. Since Northumberland was formed in 1772 from parts of Lancaster, Berks and Cumberland, I doubt Derry's history preceded it's formation. Hope this helps point you in the direction of search.
