An oddity - the 1949 Wichita City Directory lists Lorentz and Gladys E. Schmidt, parents of Lorentz Jr. There is also an entry for a Betty M. Schmidt, widow of Lorentz Jr., on the same page, preceeding column. My only guess is they were divorced by 1949 and she somehow got listed as a widow rather than a divorcee, since Lorentz did not die until 2001 (EAD)
