New Work & Research

Does anyone have information on the life and career of this British Army officer, who was a commissary officer in North America during the American War of Independence? He was a friend of Burgoyne, apparently still in America in 1780, and died (I think) around 1797. I am particularly interested in his whereabouts between 1775 and 1785, as well as any information about his life following the AWI.

Thanks
