I consulted the Cleveland Public Library's Necrology file, a collection of obituaries and death notices from Cleveland newspapers.
On February 23, 1924, a death notice appeared in one of the Cleveland newspapers (but when they copied it, they didn't note which one), for Kezzie Bradley (nee Cook), beloved wife of William E., mother of Sherman, Linn, Karl, Elmer, Cleo, Mrs. G. V. Ahlberg, and Howard, at her residence, 6006 Broadway, Thursday, Feb. 21.
William E. Bradley's death notice appeared on June 17, 1932.It listed the same children.
I also found one from July 29, 1953, for Gustave V. Ahlberg, husband of Ethel (nee Bradley), father of Virina Peters and the late Arlyne Murray, grandfather of Kenneth, Bruce and Wayne Murray, and Kathleen and Russell Peters.
I also consulted the Cuyahoga County marriage record index, but the only marriage I could locate was for Elmer, to Cecil V. Deen.
