I am trying to trace a Captain Cattanach who was in The Ediburgh War Hospital at Christmas 1917. He gave my Grandfather Henry Appleby of Uphall/Livingstone, West Lothian, Scotland, a book about the Royal Scots Regiment. My great grand father, Donald Saddler Appleby, apprently saved Captain Cattanach life in WW1 and they were reunited at The Edinburgh War Hospital in 1917 when my Great Grand Father Donald was sent there after being injured sometime in 1917. Donald died of his injuries on 23rd November 1918 but Captain Cattanach apparently suvived the war. My Great Grandfather was a Sapper in the Royal Engineers 2nd Res Battillion SERVICE NUMBER 299658 and signed up in 1914. He was posted to France in 1915 and died, as stated on 23 Nov 1918. I would like to know if there are living realtives of Captain Cattanach, apprently of The Royal Scots but possibly of the Cameron Highlanders and if they can cast any light on this story. The Captain may well have kept a diary or sent letters speaking of the events which saved his life. I would be very interested if any one from the Cattanach family Scotland, circa 1900's - present could help.
