I work on the Capt-Commandant James Mackay Family. Lost of information about him on the Web. I had hoped that I could find some family member that would like to have the picture of the John Mackey that I have. I have found James' names spelled a number of ways. So please don't let yourself get stuck on only one spelling. I have James as Macky, McKay, Mckie, Mackay and Mackey and several others. In Cananada he was known as Jocque MacKay, for the Spanish Don Santagio MacKay and for the English James MacKay and I believe in Scotland he was probably called Shamas MacKay. All stand for James.
James MacKay was the last Commadant for the Spanish in the St. Charles District of the Louisiana Territory. It was his map of the Missouri River that was the most complete map used by the Lewis and Clark Expedition.
