context: The father of Mark Kalpurnia, according to the Capitol fasts, bore the name Guy [3]; nothing more about its origin unknown. Presumably, Bibul belonged to the Senate estate by birth, although he was in some way a new man (not one of his ancestors was a consul). His at least relative nobility is indicated by the fact that he was early elected as the Curule aedile - before he became Mark's son Portia Cato's son-in-law. However, it is impossible to establish the degree of kinship between Bibulus and Pisons [2].
question: What was the name of Mark Kalpurnia Bibulus's mother?
