I'm responding to your message from 1999---on the outside chance you still have the same email address.
I am descended from Samuel Light and G. B. Hance through Nancy Jane Hance Pryor Burton----G. B.'s daughter. Green Berry Hance (or Greenberry, as some put it) was one of 15 children of John and Rachel Hance. But you probably know all this since it has been seven years since you posted your message.
Would love to exhange info.Will wait to hear from you.
