Here is a diagram of all the known forebears of Landron and Jessie. Its rather different than the usual sort of family treeyou might think of it as tree rings in reverse. Landron and Jessie and their children are in the middle, with their ancestors radiating outward. Each curved line represents a generation.
[Editors note: This diagram, posted only recently, is already out of date. I have so many new names to add that I am going to attempt to devise a more compact format to display them all. Apologies if you see gaps between the various sections of the diagramthis is another problem I have to solve.]
