My great aunt attended a school during the 1900s-1920s called the "Ephpheta School for the Deaf", located on the corners of Pulowski & Belmont in Chicago, IL. My aunt's name is Eugenia Kwasniewski (or Eugenja Kwasniewska in Polish. She was born abt 1900 and died in 1963, she was deaf, and she was married to Carl Johnson, a mute.
The school opened in 1909 and was possibly closed in the late 1940s. The reason I say possibly closed is that the building that housed the school was sold to Madonna High School, so I have no idea what happened to the Ephpheta School after their buidling was sold.
I have contacted the Illinois School For The Deaf to see if they had any ideas, but they did not have access to those records.
