Auguste Saalfeld obituary

Josephine's federal naturalization file carries the same Stuttgart birth date and 1909 Schwarzschild marriage, records her lawful entry under Josephine Einstein Schwarzschild, and contains both her Schwarzschild oath signature and the court order changing her name to Josephine Stone. The 1950 census then places Josephine Stone as sister of Melita Levy and Ludwig Einstein, and the California death index preserves her exact birth date and her mother's maiden name as Schweitzer. These independent records satisfy the identity bridge.

Auguste's 1965 obituary names Josephine Stone and Melita Levy as her sisters. The 1950 census directly places Melita Levy with her brother Ludwig Einstein and her sister Josephine Stone at 3897 Clay Street. Josephine's federal naturalization file preserves her Stuttgart birth date, Einstein Schwarzschild entry name, and court-ordered Stone surname; her California death index independently preserves the same birth date and her mother's maiden name as Schweitzer. Together these records provide the direct identity bridge required by RQ-005.
