This was written by Connie: "Just searched online for this book. It is "out-of-print" and not listed currently by any of the major online book-seller's.
A WorldCat Search finds the book in three library collections:
New York Public Library Library of Congress Library & Archives in Ottawa, Canada.
The author, Ida Florence Wright Crozier, published a Fletcher/Crosier book that is available in more than half a dozen libraries, mostly in central Canada and the United States.
I did not check to see if the Church of Latter Day Saints library has a copy.
Not an easy task to find. Perhaps the person searching can locate a Lieutenant John Crosier descendants, who has the book in his personal library and would be willing to make photocopies or otherwise, share.
To learn more about Lt. John Crosier please join Ancestry.com There is extensive info. there including his biography as it appears in the book, a photo, descendants etc.
It is possible to take a trial membership and explore what's available to decide whether to continue as a member or to take simply a one month's membership for his immediate researching."
