The address for the library & society is: Lankerd-Thomas Genealogical Library; Armstrong Co. Historical Soc. 300 N. McKean St., P.O. Box 735 Kittanning, PA. 16201 With the Library name first on the envelope, the libarian will be the first to open it. We are backlogged now with requests from November. Usually if you have a brief request such as materials list etc. We try to get it out right away. Our small volunteer staff just get over-burdened but we do answer all inquiries. Connie Mateer
