Kevin - I recall in long ago family history a great uncle George Armour who lived in and had dealings with the railroad in Argentina. He was probably in his 20's or 30's in the 1920's. I only met him a couple of times and don't know a lot about him other than his parents lived in Duluth, Mn. Hope this is of some help. I am starting to research George's (and my grandmother's)side of the family.
