Margie: Sorry,but know nothing about Clark Whitaker except that I think he is my g-grandfather. Will be doing much research on him (hardly know where to start), but at this point, do not think he is of your family. All I know is he m. Catherine Beardsley and had son, Sylvester, which is near but far from Sylvester. Also, I believe his father to be Abraham-5, who m.Betsey White who is Clark's mother. Again, ?? Try me again in a few weeks and I may be able to tell you more if you are still looking. Good Luck!! Marie Whitaker Sheldon
