I'm not very familiar with papal genealogy, but I have no doubt that many popes have had royal ancestry. Have any in recent memory been of royal or noble descent?

The reason for my asking is the intense fascination generated by the accession of the first North American to the papacy: genealogists have uncovered a colorful pedigree -- literally (his mixed race ancestry).

Evidently he is distantly related to a number of celebrities in the entertainment profession (Madonna, Justin Bieber), as well as Hillary Clinton -- but not the orange man.

I wonder if he has any blue blood, however: I have similar questions for his immediate predecessors on the throne (Francis, Benedict XVI, John Paul II).
