Muriel, I'm also researching St. John's of Idaho Falls, Bonneville County, Idaho. I'm hunting for the descendants of Mary Dora and Theodore St.John Sr.; I had a look-up send me their obituaries and she sent me the card file for Timothy B. St. John, born: May 14, 1882 in Esbon, Kansas
died: November 15, 1948 in Idaho Falls, Idaho. parents name was: David B. St.John and Melvina Mary Crofutt; spouse Clara Baldwin St. John. She sent this to me and I don't think he is connected to my St. John's. If you think he is connected to my St John's I would like to hear from you. Mary and Theodore had the following children; Fred,Theodore Jr. and Louella Mae. Fred and Theodore lived in Idaho Falls; Louella lived in Colorado. Would like to hear from you if this is part of your St.John family.
