I do not have the actual boundaries of this tract but it includes the area that is Pleasant Valley today and includes Cub Run. In colonial times it was in Cameron Parish. I believe that it originally was set off in Loudoun and then when Washington D C was set as the capitol this expanse of land was given back to Fairfax. I am not sure how many times portions of it have gone back and forth between the counties but I know that in the 1930's that section was in Fairfax and then in the early 50's at least a portion of it was given back to Loudoun. The area in dispute was never in Fauquier and I have never heard of a land dispute between those 2 counties My mother grew up and graduated from Herndon High School in 1949 and yet most of my entire life it has been considered Loudoun County Susan
