German-born Rosanna Dyer Osterman settled in Galveston, TX in 1838. Osterman was instrumental in the founding of the first Jewish community in Texas. She brought the first rabbi to Texas in 1852 to consecrate the state’s first Jewish cemetery, and the first-known Jewish service in the state was held at the home of her brother Isadore Dyer in 1856. In one interesting incident, she helped the Confederates retake Galveston from the Union Soldiers during the Civil War.
