The only known copy of the book is in the Family History Library at Salt Lake City. I have had the book in hand and it appears to be self publihed by Dr. Harold Barker, Maurine Cliford and a third person( I cannot recall his name). The book is on film and can be ordered for viewing at your near by LDS Family History Center. I have a copy that I paid to be at my family history center to keep on file. I do not know the relationship of Dr Barker to the Briggs but Miss Clifford is a descendant of John and Constance Peacock Briggs.
