BOCA RATON— Before World War II in Munich, Lilly Rose’s family owned a successful two-story department store, selling ladies’ and men’s clothing. When the Nazis took over, the family’s business and life were shattered. Rose’s father was killed, her mother fled to a farm and Rose, now 91, escaped to London. Rose, who now lives in Miami, remembers the family owned a life insurance policy through insurance giant Allianz, but it wasn’t until last year that her son found his mother’s and her parents’ names on lists of beneficiaries that Allianz was forced to provide to the International Commission on Holocaust Era Insurance Claims. Sabia Schwarzer, Allianz spokeswoman in Washington, D.C., said Friday the insurer has made good on all claims it was required to pay by the commission. But survivors and their heirs, including the Roses, don’t agree, and want Allianz to pay claims they say total $2 billion.
