Hi. .. responding to your (very old) request regarding information on David McClure born 1799 in Scotland. David McClure (and wife Ann Galt) were also my great, great, great grandparents. They had 13 children, all born in Scotland. I am a descendent of their daughter Catherine Ferguson McClure (1835-1922).
The family emigrated to Ontario Canada sometime in the mid 1800s. I think it was the entire family, including David and Ann and their children, but do not know details.. also wonder under what circumstances they left Scotland. In Ontario, in 1862 Catherine Ferguson McClure married John Mills. They had 5 children, including my great grandfather William Dickie Mills (1866-1971).
William had 4 sons, including Dickie Mills, who is my maternal grandfather. They lived in the London, Ontario area for many years. I remember visiting William when I was a small child. He was proudly wearing his tartan tam (which he always wore), and stoked his Scottish pipe with cherry tobacco. He took me for walks and carried pickled hard boiled eggs (to give to me) in his sweater vest pocket. William lived to be 104 years old. He served in the military, as did all of his sons (one who was killed in WW1). On his 100th birthday Queen Elizabeth II made a special visit to him at the Veterans Home in London Ontario, as the oldest military survivor of a particular battle (rebellion) in Canada.
Attached is a diagram with information on David McClure and his descendants/family tree. I hope this helps to address some of your questions.
