Amazingly in 2011, 14 letters surfaced sent by Bronia, her aunt Basia, her grandparents, father, mother, and sister to relatives in the US.  The letters were written in 1939, 1940, and 1941.  Some letters were written in Yiddish, other Russian, a few in Polish, and many had notes from several people using different languages.
