Dave, I believe you are my nephew and we are both looking for the same David St John Vincent Donald Stuart. He was my Grandfather as my father was Donald David Braybrooke Stuart and your father Robert Stuart was my half brother. I only met Robert once and I was too young to remember much. My brother John Francis Stuart is in Scotland on a bones trip to find the Scottish Stuart connection as we speak. I have a lot of history and documents that may interest you. What country are you living in?
