My great aunt Olga Marx Goldberg survived Teresinstadt and traveled on the USS Perch to New York in 1946. She lived with her son Werner Goldberg at 112 West 112th Street, New York, NY. Olga was the sister of my grandmother Thekla Marx Mendels. Thekla was deported and perished in Sobibor. I am looking for Olga's son Werner and his descendants if there are any. Jacqueline Mendels Birn
