My relative, Rose Kennedy (~1910-?) sister of Marie Kennedy (1906-1931), living at 753 Sterling in Brooklyn, NY, according to the 1930 census, married someone named Sebald according to Marie's 1931 obituary. Marie and Rose were the daughters of John F. and Sarah (McLaughlin/McLoughlin) Kennedy. Any connections or suggestions are welcomed. Most of this fammily is buried in St. John's Cemetery.
