A number of months ago I purchased a copy of St. Johns by Cameron Udall. It is part of a series of books called "Images of America" and this edition was published in conjunction with the Arizona Historical Foundation.
It has five chapters: The Making of a Town, Taking Leave of Arizona by the Winchester Route (outlaws and crime), Dam That River, Educating St. Johns, and Pride and Perseverance (general history).
Each chapter starts with a short essay on the topic and then includes many high quality photos with extensive captions.
For a sample of the photos in the book, you can look at the google books online version.
There are many family photos in the book, including many representatives of the Christensen, Overson and Jarvis families. The photographers are not identified, but a large number of the pictures were undoubtedly taken by Charles Jarvis or Margaret Jarvis Overson.
Here is one of my favorite photos from the book:
