I've studied your census information and I think we have a match.My Andrew Dunlavy matches your 1870 census - b. 1808,lived in KY ( my notes say born in VA), m. Lucinda Jacobs b. 1816 KY.They had a son James Gillespie b. 1839 KY - who matches your 1860 census info. - he was a captain in the Civil War.I have more family notes on family members, if this is of help to you.
