Who is Virgilio Vivacemente from Life Expectancy and what is their importance?

Paterfamilias to the Flying Vivacemente's, Virgilio is the aging patriarch who fears the loss of his youth more than everything else except not having someone to carry on the family tradition. Virgilio wanted a son so badly to carry on his name and tradition. To get the purest lineage possible, in an act of madness he impregnates his own daughter Natalie. Natalie then runs off with Konrad Beezo, a clown in their traveling show.
