Butler County Poor Farm, records index 1900-1963 –  Births, Deaths, Burials, Census – The Butler County Poor House, also known as the County Home or Poor Farm, was opened on 25 Oct 1900 to accept the homeless and infirm who were unable to provide for themselves. It was reorganized in 1963 as Sunnyview Nursing and Rehabilitation Center. The Stewards (superintendents) maintained various records, which were aptly called “Steward’s Register of the Names of Paupers Admitted to the Butler County Poor House”. The admission records commenced in 1900, with the opening of the Poor House, and end in 1963. Additionally, every three months a Census of residents was entered into the Register. Consequently, residents were recorded at the time of admission and in each quarterly Census during their stay. While most people were from Butler County, neighboring counties also placed residents at the Poor House.
