Shirley, I can't reach you or your web page. Did you change servers ? My Loudons were in Nelson County, KY in 1795 when John Loudon/Loudoun married Dorcas Masterson, daughter of John Masterson and Lourannah Willett. John and Dorcas moved to Henry County,KY by 1796 where their 3 children were born: James Loudon b 21 Oct 1796, married Elizabeteh Chapman in Georgetown, Brown County, Ohio, Charles Loudon who married Ellen Sells (I think in Clermont County, Ohio), and Nancy Loudon who married Ebenezer Hatch.
I have quite alot of information on John Masterson. John Loudon apparently died sometime before 1806when Dorcas, then a widow moved to Brown County with her 3 children, where her sister Rhoda and Jemima (wife of Cornelius Washburn) lived. She remarried, in Ohio, Joshua Jordan, and 3 more children. She died 13 July 1863, and is buried in Ripley, Ohio.
