Wichita Eagle (Wichita, Kansas), Friday, September 8, 1972, page 14:
"Arthur J. Koleber, 50, of 156-1/2 North Market, barber, services at 1:30 p.m. Friday in Broadway Mortuary. Survivors include his son, Arthur D., Edwards Air Force Base, California; his mother, Mary, WaKeeney, Kan.; four brothers, Ernest, Lawrence, Kan., Ed, Carlsbad, Calif., and Harold and Laverne, both of Los Angeles; and five sisters: Mrs. Minnie Nowlan, WaKeeney, Mrs. Martha Kroeger, Denver, Miss Alvena Koleber, Fairbanks, Alaska, Miss Elenore Koleber, address unavailable, and Mrs. Ester McChaw, Dayton, Ohio."

This could possibly be a wife. Only other Koleber buried in Wichita, KS, per findagrave as of 28 Jul 2015. But she is in a different cemetery. Also, I found her obit and it doesn't mention any children or a husband.
