I search the internet often as I lost a camera and I am hopeing that someone will at least post the pictures so I can get them back. So I seen these beautiful old pictures and did a search on Mary Jane Nelson and thought maybe she is related somehow to you. I hope she is. These are a few of the photos that the person found and you can go there and get them if they belong to your family
Anyway I found this site and on this page http://www.ifoundyourcamera.net/page/5/
they are looking for Mary Jane Nelson Sept 6, 1946. It seems to be from Canada as she talks about it in the book a lot with the photos. It also discusses Peace Arch in Blaine, Washington. Laralee State Park, Rose Arbor, Lions Gate Bridge seen from North Vancouver ferry, Capilano Canon Vancouver, Parliament Buildings in Victoria B.C. There are photos of a Flood on the Snoqualmie River looking towards Mt. Rattlesnake. There are some of her parents, her house.
The book is a teal blue (faded) cloth material with pinkish flowers and leaves.”
