William is also my ggggrandfather. My gggrandfather was his son James Mackhattan Wilmot. I have some info on William, his wife Elizabeth Graves, and his second wife, and their children, grandchildren, etc. I have been to his grave at Pleasant Hill, Cass County, MO. Matilda & Malinda married brothers, William & George Dunlap. Unfortunately, I don't have been unable to be positive about William's ancestors. Elizabeth's family is well documented. Her sister Cynthia and her husband William Nichols are my ggggrandparents on another branch! I do not have my paperwork w/me right now, but will send more info when I get home. Would like to compare info.
