John Boggess - Clermont County Ohio

I'm interested in John Boggess, who came to Clermont County, Ohio circa 1802, m. Luticia Mifflin.  Justice and state legislator in Ohio.  Buried Clermont County.  I have significant information on him, but very little on his wife or parents.  Am looking for additional clues on him via siblings and other family members - he was probably in Kentucky before Ohio, may have worked in South Carolina as a surveyor, and was probably originally from Virginia.  Thoughts, clues, appreciated!
