Starting Sept. 30, 2014, Genealogy.com will be making a big change. GenForum
message boards, Family Tree Maker homepages, and the most popular articles
will be preserved in a read-only format, while several other features will
no longer be available, including member subscriptions and the Shop.
In a booklet I have on Prince William Co., VA, "Crossroads and Corners" by Eugene M. Scheel is the following: "Newport, established in 1787, was to draw commerce from Dumfries, whose deep water was rapidly silting in. Cuthbert Bullitt, who lived at Mount View just north of Newport, had the idea, and had thirty-five lots laid out. Since 1757 there had been a ferry here 'over ther otowmack River to the land of Roger Chamberlayne' in Maryland and in 1787, a second ferry 'from the land of Cuthbert Bullitt..across the mouth of Quantico Creek' to Carrborough, Newport's sister town, established the next year for similar reasons. Both came to naught and Mount View, atop Bullitt's Hill, was destroyed by Federals in March, 1862 in retaliation for the Confederate batteries there, set up early in the war to harass Union shipping plying the Potomac River enroute to Washington and Alexandria."
Prince William Co. has a great genealogy room, called RELIC, in the Bull Run Library. They could probably give you more information on these people.
