I think he was my ggg grandfather also. Here's how my history goes. He fathered James D Garrison, who fathered Kiefer Hannah Vinora (Garrison) Clarke. She gave birth to my mom - Leona Tency (Clarke) Sutherland. I am Judy Lunn (Sutherland) Shepherd. Grandma was known as Nora Clarke. A brother and sister married a brother and sister (Clarke's and Garrison's) and there were a bunch of double first cousins.Where do you fit in the mix?
