1880 Census

This is an index to the 1880 Census of the United States, Butler County, PA.  For now, this index is listed by each township, alphabetically within the township.  This work has not been proofread, nor have we completed trying to fill in the names that contain question marks.  Those are names that the transcriber doing the township could not decipher from the census record.  No claim is made as to the complete accuracy of this transcription.  Anyone wishing to help with proofreading these townships should contact us.
