Also I unearthed a commemorative plate from the Corliss Street Baptist Church, marking the church's centennial in 1958. This would have been right near my mother's childhood home, which I remember her saying was on Corliss Street. (The church itself, however, is located on Middle Street.)
Almost half a century later, the church is still going strong, and they even have a website (Corliss Street Baptist Church).
The picture on the website looks just like the one on the plate!
