Hi Julia: Based on my very limited knowledge this is what I understand: Redstone is the name of a township in Fayette County, Penn. I believe there once was a city/town in Fayette Cty, Penn called Redstone Old Fort. This is now Brownsville, look on the Ohio river for it. Now a question for the list, are there any books, booklets, write-ups on Redstone Old Fort that anyone may know of. I know it's in Fayette not Beaver, but at least for my ancestors it was a 2-4 year stopping place before they moved permanently into the area south of the Ohio in Beaver County. Time Frame: 1790-1805. Any help would be gratefully appreciated.... thank you kathy olson plano, texas
