Sylvia's maternal grandmother, "Grammy" Greenwood Schober (b. 1887) had six siblings. All left Vienna, Austria, for the United States. Grammy's brothers Joseph Greenwood (b. 1876) and Otto Greenwood (b. 1877) lived in St. Louis, Missouri, and worked as waiters in hotels. In 1951 Otto Greenwood hanged himself. He was 74, married, and 15 years retired from his waiter job. The Missouri death certificate says "Suffocation by hanging in his house Dec. 28 1951 about 12 noon."
Otto Greenwood was Aurelia Plath's uncle and Sylvia Plath's great-uncle. There is no reference to him or his death in any known Plath documents. He had a wife, Angela, and two grown children. Like Aurelia Plath's waiter father Frank Schober, Otto Greenwood belonged to the International Geneva Association for hospitality workers. [1] Greenwood was cremated on Dec. 31, 1951.
The Gregg shorthand character preceding the coded designation "974X" under "How did injury occur?" says "respiration."
