I would like to know which county would have the land records for the area of Plumcreek Twp. prior to the formation of Armstrong Co. I have to rent film at the local FHC and would like to get the correct one on the first try. Also, was Cowanshannock Twp. once a part of Plumcreek Twp.? Is there a good source that explains the formations of the townships in the county and how they evolved? I have a map of the current townships but would like to know what was where at the early census dates. Thanks for your interest. Regards...Ron mailto:mcc533@scsn.net
