I went to www.WikiTree.com which has a thriving project for famous persons. I quickly found Hillary (Rodham) Clinton's profile (Rodham-1) and clicked on the "Relationship to Me" link (it's under the person's name next to "My WikiTree), and the relationship chart appeared (three screens shown):
So, Hillary is my 18th cousin. Our common ancestor for this relationship is Pierre de Luxembourg (1390-1433).
On the right side of the first screen above, there is a box that says "Explore more: 37 common ancestors were found between Hillary and Randy within 25 generations. To view the relationship trails, select the common ancestor here." That dropdown list provides the names of all 37 of our common ancestors, according to WikiTree, back 25 generations or less.
But WikiTree doesn't show Donald Trump as a descendant of John of Gaunt. It doesn't show that Hillary Clinton is a descendant of John of Gaunt, but is a 2nd cousin 19 times removed to him.
