Bilss Family Links to Famous Cousins

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.
