Dear Laura: (Wiggs)
For Franklin County, PA information contact the PENNSYLVANIA ROOM (L. DEAN CALIMER COLLECTION) of the Alexander Hamilton Memorial Free Library 45 E. Main St., Waynesboro, PA 17268 - Phone (717) 762-3335. If you live in the area or get to Waynesboro this is a great research location. They also have a collection of the US Census microfilms of Franklin Co.
You may want to contact the library or Mr. L Dean Calimer. Mr. Calimer is a researcher/genealogist who, after he has completed an assignment, donates the results of his research to the library. His contributions are made to the L. DEAN CALIMER COLLECTION and it is loaded with ring binders full of research on many Franklin Co., families. His address is 136 N. Potomac St., Waynesboro, 17268 - Phone (717) 762-6736. I understand that he has been ill so if he or the library can't help you they may be able to refer you to someone else.
Kittochtinny Historical Society may also be able to help you. You can write to them at 175 E. King St, Chambersburg, 17201. Be sure to include a SSAE; a small donation towards photocopies is appreciated. They ask for 20 cents per page for nonmembers and 10 cents for members.
Good luck, Jack Novicki
