Jean, Essex Co. is along the south side of the Rappahannock River southeast of Fredericksburg and Fluvanna Co. is south of I66 southeast of Charlottesville, both 50 or so miles from Fauquier Co. There are several Clarkson families with roots in VA. If you look at USGenweb for Clarkson you will see a lot of correspondence. I have posted several times and the only response I have gotten is that Henry's lineage is not known. That's why I am looking through the Turners. Henry appeared in the Fauquier tithe list in 1781 and in the minute book in 1784 when he was assigned responsibility for a portion of road west of the village of Hume in the northwest part of the county. He subsequently leased land in the Manor of Leeds and left several tracts to his daughter Martha and to his son William (from whom I am descended). I don't remember Dorothy being mentioned in his will. One of William's daughters, Eliza L. S. married Jaquelin Marshall of whom you write. I believe that Henry may have been in MD. before he married Dorothy. There should be a marriage bond on record there. Do you have a contact to check that? Bill
