Very nice finds!
Mythbuster....I hadn't noticed that reference to Mary in the 1918 trial transcript. So it looks like she was having health and mobility issues as early as 1918.
Black Sheep....Yup the 1920 census shows that Raymond Harmon lives at the same address as Mary Rutherford:
I am not sure but it looks like the census taker used ½ notation to indicate sublets. So at 128 N. Eastlake Avenue lived Mary Rutherford and William P. Jones (age 78) both as their own respective "Heads" of the family. William's family included his widowed daughter Maria Harmon (age 55) and her four grown-up kids and a son-in-law. Raymond Harmon, music teacher, was one of Maria's sons. As his Who's Who entry states: "Began his vocal study with Holmes Cowper, at Drake University, Des Moines, Iowa, in 1912. Studied in Chicago with Lucille Stevenson and Charles W. Clark, at Bush Temple Conservatory. Later he studied with Louise Grandjean and Sig. Trabadello, in Paris. Has held excellent church positions in Des Moines and Chicago, and appeared in light opera in various parts of the U. S. In concert and oratorio [he] has appeared in the U. S., England, and France" (p. 74). Here is the entry for Malcolm's address:
And here is Malcolm's 1917 draft card, which gives 128 ½ N. Eastlake Avenue as his address. This is the same address that Mary has in the 1920 census.
