She was one of the organizers of the Grand Army of the Republic Women's Relief Corps and she served as their second National President. She was known and described at the time as a "Freethinker" and "Active Suffragist." Sherwood was the wife of Congressman Isaac Sherwood and she was known as "The Poetess of the Congressional Circle." She died in 1915 in Ohio although her funeral service was in Washington, D.C., a tribute to her national prominence.
