If this is any help. I'm quite sure my great grandfather was Capt. Christopher Valley. His son, my grandfather was Robert Adolph Valley. Not 100% on the middle name Adolph. My Grandfather had 9 children with Florence Normand-Valley and was killed in the years around 1917-1919. One of my cousins had researched archives for a the story of the Capt. This was about 25 years ago. I could get some of the career educators and archivists in my family to possibly provide more.
