There was a Lewis Memorial Maternity Hospital of Chicago's south side at 3001 S. Michigan Avenue, pretty much on the corner of Michigan and 29th. It was an archdiocese hospital run by Sisters of Charity of Providence. Check this site out: [

And don't quote me but I think the building it was in was a rather tall building, that at one time was a hotel for the World's Fair in 1893. I hope this helps!
