I am looking for any information for the Startzman Pumps business located at 116 N. Washington, Wichita during the 1900 - 1930 era. Business was co-owned by Jacob Startzman and his son Ezra Startzman. Ezra was married to Effie M. Startzman, DOB 1820, Died 1953. I am searching for Effie's maiden name. She was my grandmother.
