Known firstly as the informant of her father's death; she is described as a factory owner's wife.

Her marriage to Malwin Wendriner is taken from the JRI-Poland record of Margarethe Wendriner's marriage to Arthur Lemberg; this record names Malwin Wendriner and Flora Troplowitz as Margarethe's parents. Evidence that this is the same Flora Troplowitz as the informant of David Troplowitz's death is provided by Arthur Lemberg vouching for her identity on the death certificate.
