I knew that Green Plunkett was the first blacksmith in Glasgow at the time of its' founding in 1832. The census records do not show a David in the family, however, and I can find no reference to Green's family being involved in any fashion in the war or in any raids by either side.
I did obtain a copy of the "Other Noted Guerillas" book today. It is very interesting and the chapter on Jackson confirms much of what I had known of his character. I note that he evidently had a relationship with Fanny Duffy of Fayette who lived with a Hackley family. There are still Hackley's in the area.
I also was able today to make a copy of the article in the "Daily Missouri Republican" RE the capture and execution of Jackson.
