Although this is an older posting, here is what I have on Ruth Bailey KNOX (my 1st cousin 3 times removed, or rather, the first cousin of my great-grandmother Emma Bailey MINCHER).
Lavona Ruth Bailey was born 1909 in Idaho, the daughter of Taylor L. BAILEY and his second wife, Lena JACKSON. Some sources claim Ruth died in 1935, but I have not found a listing yet to confirm that. She married Wallace Edward KNOX on 23 September 1926 at Mountain Home, Elmore county, Idaho.
Lena JACKSON was first married to Charles E. DAUGHERTY on 16 January 1904 at Soldier, Blaine county, Idaho. Son Athol Leonard DAUGHTERTY was born 9 September 1904 in Idaho and died 20 November 1992 in Lassen county, California.
Taylor L. Bailey was born 19 September 1869 in Iowa, and died 27 November 1930. His first marriage was to Mary S. Russell in Iowa. She was born 24 June 1871 in Des Moines county, Iowa and died 19 February 1897, with burial in Edwards cemetery. Their only child, son Russel Bailey, was born 27 July 1896 and died 10 November 1896 in Louisa county, buried at Edwards cemetery.
Taylor BAILEY and Lena JACKSON were married 1 June 1907 in Blaine county, Idaho. Taylor and Lena were divorced by the 1920 census. Taylor died 27 November 1930, and was buried with family, including his parents, first wife, and son, at Edwards Cemetery near Oakville, Louisa county, Iowa. Lena died 26 June 1958 in California (Lassen), under the surname of DAUGHERTY, which she may have resumed after her divorce from Taylor Bailey.
Taylor's parents were Percival Deshield BAILEY and Deborah T. WATERHOUSE. If you want more information, let me know. I've got a lot more than can be easily transcribed here. Here are a few census transcripts concerning the family:
