My MIL and FIL did that! They wanted to elope and she was too young in PA but old enough in W. VA.

I have a couple of questions for the group. When I was back home in the Kittanning area, I noticed that the wall at the Kittanning courthouse that commemorates the men killed in the various wars that Armstrong County men participated in, had no names listed for the Revolutionary war but quite a few names for the "Border Wars". My questions are these; Who were the border wars with and when did they take place? Also, Did Armstrong County and vicinity not have any residents at the time of the American Revolution or did the war not extend that far West? Thanks to anyone who answers. Sandy Lockhart Mundinger
