There was a Henry Moffett, one of the descendants (?) listed on the above profile, in Fauquier County, Virginia, in 1778. He is listed as a tithable on the Fauquier County tax list that year per Joan W. Peters, The Tax Man Cometh, Land & Property of Colonial Fauquier County, Virginia 1759-1782, Willow Bend Books, Westminster, Maryland, 1999, page 30.
There is no way of knowing if this is the same individual but there are some similarities.
