Thanks very much Dennis. The links you shared led me eventually to a page belonging to The Cresap Society, which says that Shipton was sometimes written Skipton but has been renamed Oldtown. Oldtown is about 15 miles east of Cumberland in Allegany Co., MD - in fact, almost as far east as you can go in the county, which means it's near the border with Washington Co. However, it's still about 78 miles from where Leonhart Wiest/Leonard Weast lived in 1793. Leonard "Weazer" disappears after 1783, which in fact is the one and only record of that name that I've been able to find anywhere in the U.S. All that makes me think it more likely that he is the same person as the Washington Co. Leonard Weast.
