For me this Ida Schimmerl does not exist.
Probably the Benno's wife is Bertha Shimmerl, born in Vienna on May, 4 1894 and dead in Vienna on August 28, 1968.
To be sure one should check the wedding certificate on Aug 30, 1925.
I wrote in a different place that parents of Benno Schwoner are wrong (see Jenny Schwoner)
Also, Vilma Lawner was deported together with her brother. She was not found before because her family name was wrong:
LAWSNER instead of LAWNER
