Edward Young, Planter - birth and death dates of Edward Young

Finding out more about Edward Young has just about driven me nuts. I cannot find out more than he was a planter, Whig, Episcopalian, and the names of his wife and children. I'm a direct descendant of Edward (through Henry). I'm pretty sure the last date of his estimated birth is incorrect, since he had a son, Henry, who fought in the American Revolution. Since Kerenhappuch was born in 1741 ( her christening is documented), I believe Edward was either a bit older or younger than she, but not young enough to be born in 1771. They did have a son named Edward, who was orphaned and asked that a Mr Pegram be appointed as his guardian.This was in the 1780's, I think.

If anyone has any more information, I would love to know!
