Jeremiah Jordan's family

Jeremiah Jordan was the brother of my ggggrandfather Sampson Jordan(b.1805). They are the sons of Andrew (b.1760) and Lettice Jordan of Pendleton County, Virgina, now Highland County. I know they had a brother they call Andy and a sister Rachael. There are other children but I only am sure of these from my own family records. Andrew was the son of John and Ann Jordan who came from Ireland during the 1760's. They lived on the Bullpasture mountain at the border of Pendleton and Highland Counties.
