Here is an up-date.William Hazelet Titus who was from Minnesota. His wife Etta May Westcott was from North Dakota. So the book you are looking for must be at the University of Minnesota. More info can be located in the 1920 census for Pocatello, Idaho where they were living. Alrhough all the children aren't listed, Eatta's parents are. If you need that info let me know.
