Built in 1869, this handsome building, which is now Camden's public library, is an excellent example of Greek Revival and Italianate architecture. It is named after Andrew Thomas, a prominent figure at the time who worked as a banker and grain dealer. He was also a Jackson Township Trustee and a founder of the Camden Bank. The home was added to the National Register of Historic Places in 1984.
After Andrew Thomas died, another man named Philip Ray bought the house and married Thomas' widow. Ray died in 1922. The house then became a parsonage for an Episcopal church in 1925. In the 1940s, it was a municipal office building and became nursing home until 1968. Trustees of the library bought it a year later. The library was founded in 1928 and opened its first location in a pharmacy a year later. It moved to another building in 1950 where it remained until 1969.
