This collection contains the names of approximately 1,000 Jewish survivors who sailed from Sete, a small French port 200 km west of Marseille, to Palestine in 1946. These records come from a book called Underground to Palestine, which was written by one of the passengers named I.F. Stone. Some of the information includes the name, age, birthplace, and the place in Israel where the people settled.
