Wm Mockbee is my gggrandfather. i am related through his daughter Mary Francis. I cannot find anyone in this family after the 1860 Missouri census. My ggrandmother shows up getting married in 1876 in Springfield, Illinois. I find one son James in the 1870 census, but no one else anywhere. Its as if the dropped off the face of the earth.

I also agree that Tilman is Wm's father, but no real proof can I find.
