Regarding "The Last Wagon West"... My aunt Iyone Gillis is the mother of this crew. They crossed the US and parts of the former Soviet Union in the wagon. I have heard from another relative that there may be a book in the works regarding this. They have been trying to get my aunt to write one for years, but now one of her daughters may be doing this. If I hear anything else, I will post it! Thanks for your interest our really unique family story!
