Thanks, especially to Robert Murowchick for the articles. Seeing them led me to do a search of my own at Newspapers.com, and it is clear from the results that the club was first located at the address on Indiana Avenue, though it subsequently relocated several times. A short notice in the *Inter Ocean* on 13 Oct 1907 announces the formal opening of the Deborah Boys' Club at 1813 Indiana Avenue. An article in 1909 mentions the club at the same address. An article in May of 1910 reports that the club has just moved from 1813 Indiana Avenue to 4044 Prairie Avenue, and an article in August of 1912 reports that it has just moved from that address to 5930 Prairie Avenue.
