markemark on Family Tree Circles

If anyone knows how these people in this list were figured (where their family trees are available), please let me know. This list is something I reformatted and edited from Ancestry links, yet it still has a mistake about the Bushes, I think. It sounds neat, but it's here-say until I find more info.
