That is interesting....wonder what the MacGregors did to piss off James VI? The genealogy thing can be a huge deep rabbit hole with a zillion side tunnels.
On a side note, I read a lot of old 50-60's paperback westerns that I pic up from friends/family/secondhand stores. Inside the middle of one I found what I though at first was a bookmark, but it turned out to be a envelope with a 1 cent stamp on it. It was a letter home from a Union soldier to his brother who was a Captain in the North's navy. The three page letter is fascinating and names others in his unit, where they had fought and what infantry camp life was at the time. When I joined Ancestry.com to research my family, I drug out the letter and discovered the author was killed in the battle of Rapahanock Station Va 1863, and the brother killed when his ship(USS Narcissus) foundered in a Gulf of Mexico Hurricane and blew up on a sandbar at the entrance to Tampa Bay in 1866.
Talk about a rabbit hole, this letter is big one. Why the heck was it in a old western dime novel? Who put it there? Through Ancestry, I located the only surviving relative of that family and I am sending him the letter as soon as I can get it professionally photographed and transcribed. Amazing stuff I tell ya...........I might be writing a book about it.
