Bert and Maud celebrated their 50th wedding anniversary in September 1949. They lived at 636 Forsythe Street and the nearest cross streets are Nevada and Navarre.
Bert died 30 Mar 1955 at age 83 and Maud died 8 Sep 1967 at age 86. When they died, their only surviving child was a daughter, Mrs. Beth WEISSENBERGER of Toledo. When Bert died, his survivors also included two grandchildren. When Maud died, her survivors included two grandchildren and two great-grandchildren, none named.
Beth must have been Elizabeth A., listed as their 19 year old single daughter in the 1930 census.

Could Elizabeth/Beth have remarried/divorced, 1940-68?
To determine where Ann or John are now, you would need to first find the obit of Beth and/or her spouse. Beth is most likely deceased; she would be at least 92 now.
There are four listings for WEISSENBERGER in the current telephone book and none are A., Ann, J. or John.
