Though temporarily thought missing or dead (maybe, see below), Maud survived. She went on to marry in 1909 — to William Edward Boyes — and in 1915 became superintendent of the Legal Aid Society, a blend of two earlier organizations, the Protective Agency for Women and Children (with which she was associated in 1903) and Clarence Darrow's Bureau of Justice). The organization worked to protect women, children and the mentally ill in the courts. In 1912 she was one of the founding members of the National Alliance of Legal Aid Societies.
Maud lived at 31 West Lake St. (or at 79 Dearborn), was born in Iowa, and had two brothers, Earl and Paul. Their father Walter was an Ohio native and her mother was Lamire "Myra" D. Parcells, b.1846. Brother Earl was born in Illinois in 1868.
According to the 1910 census, Maud and her husband lived with Maud's brother, Earl, who worked as a grocery wholesaler clerk, while William clerked in a furniture store. Also living with them was Maud's mother, Myra, and a nine-year-old nephew, Paul D. Parcells jr.
Maud's husband William died while on a trip to London in 1921. In 1925 she traveled to London with Kate and Gloria Gartz.
Among the victims was a party made up of children and adults from the Gartz, Guthardt, Theni and Fahey families. Of six, only one survived.
