As I'd noted previously, I have set up a DNA project w/ Family Tree DNA. In comparing my results w/ some I found on the web, I came across results for another project, Dooley/Duley. My 12 loci were only off in one location from that of two Duleys who were tested. This means there is a very strong likelihood of a common ancestor in the last 200-720 years. The Duleys have documented their family back to the mid 1700's in Kentucky and Maryland. If someone should have Cooks, or more particularly, Duleys, in these areas, this research might be a portion of your inquiries. Glen Cook Descended from Wiley P (Parnell?)Cook of Yazoo, MS, born 1862.
