Rose Sarah was my great aunt on my father's side. Her mother's first name was spelled Merilisbeth and she went by the name of Mary. She had younger sisters, Lydia Minnie, and Mary Paulina and a 1/2 sister (possibly an older sister) named Josefine Reibant. Sara's parents immigrated from Russia to the USA in 1907.
