Margaret and her sister Julia were home with their parents until they died. At the time they were all living in Sedan. In 1913 or 1914, they moved into the hotel building in Sedan, owned by William E. Martin, and ran it for two or three years. "The Martin girls," as they were referred to locally, then went off to be trained as Red Cross nurses in Helena, Montana. In 1920 they returned to Sedan for a vacation and homecoming.
Shortly after they returned to Montana Margaret married Chris Miller, a farmer from nearby Townsend. However, Margaret died within a year or two. Many of the brothers and sisters went to attend the funeral by train. Margaret is buried in Townsend, Montana. There were no children.
