Ludwig Einstein
The primary naturalization and draft records establish this Ludwig as born 26 July 1880 in Stuttgart, unmarried, and resident at 3897 Clay Street in San Francisco. The 1940 and 1950 censuses identify him as Melita Levy's brother, and the 1950 census also identifies Josephine Stone as their sister. Combined with the established sibling identities and a California death index naming his mother as Schweitzer and father as Einstein, he is strongly supported as a son of Emil Einstein and Karoline/Caroline Schweizer and a brother of Auguste, Melita, and Josephine. The original parent-naming birth or death record has not yet been reviewed, so the parentage is not confirmed.

Evidence-backed claims
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.
Two passenger manifests document the continuous 1939 route, and two federal censuses independently repeat the same San Francisco sibling household and address a decade apart.
Ludwig's naturalization file and draft card establish the same Stuttgart-born man, with the exact birth date 26 July 1880, at 3897 Clay Street. The 1940 and 1950 censuses directly call him Melita Levy's brother, and the 1950 census also calls Josephine Stone their sister. C-019 independently bridges Melita to Auguste, while C-009 establishes Auguste and Josephine as daughters of Emil Einstein and Karoline/Caroline Schweizer. The California death index matches Ludwig's exact birth date and reports his mother's maiden name as Schweitzer and father's surname as Einstein. Ludwig's 1939 manifests also name cousins in the Laupheim Einstein network and at 3800 Washington Street in San Francisco. Josephine independently named the same San Francisco cousin, Corinne Koshland; Corinne's signed passport uses the maiden name Schweitzer, and the likely Laupheim cousin Benno Nördlinger was a son of Pauline Einstein. This convergence makes the parentage and sibling relationship highly likely.
