I was born in my grandparents house in Chicago in 1947.
6640 South Oakley was their address. (I remember their phone number to Grovehill (GR) 61520, after having your local operator send you to the Chicago exchange
It appears to be on the west edge of West Englewood, or perhaps on the east edge of Chicago Lawn.
Spent most summers in Chicago until I was 16.
It was always a tough neighborhood, being on the South Side, but it noticed it going down hill when I would visit my grandparents, still living on Oakley, around 1970.
