In my family tree, I have a David Corbin. I don't have much information particularly about him, but about his parents. Maybe this will help. I don't even know if it's the same David Corbin you're talking about: David Corbin, son of John Corbin II (born 25 Sep 1671 in Richmond County, VA; died ab. 1740 in Fauquier County, VA) and Elizabeth Smith. David Corbin's siblings are: John Corbin III (born in 1697 in Stafford County, VA), Rawley, Charles, Andrew, Elizabeth, Mary, Francis, Rosamond, Peter, and William. David's Father, John Corbin II, is the son of John Corbin I (born ab. 1645 and died 8 Oct 1696 in Richmond, VA) and Elizabeth Elliott. John Corbin I is the son of Henry Corbin (born 1629 in Halls End, Warwickshire, England and died 8 Jan 1674 in Middlesex County, VA) and Alice Eltonhead (born 1627 in Glochester, VA). John Corbin I has a sister who is Letitia Corbin (born 25 Aug 1657 in Middlesex County, VA and died 6 Oct 1706 in Westmorland County, VA). Letitia Corbin is the great great great grandmother of Robert Edward Lee (better known as General Robert E. Lee).
I have more information if you think this is the same David Corbin that I would be happy to share with you. Just let me know!
