I too am a descendent of Forrester Stainback through William Howell and William Henry. My uncle E.F.Stainback,Jr. has searched for many years the Stainback lines and has never been able to get past Forrester on that particular line. I believe Charlie Rathbun is in the same position. If anyone out there has a clue to Forrester's ancestry, there are lots of us who would love to learn about it! Thanks for the query. Good luck. I would be glad to share info on William Howell's line, but sounds like that's the part you already know the most about.
