Hey Sonny,

I am not 100% sure if Calogero is Liberio's son or grandson but if you look at the book Mafia inc. and at the Rizzuto/Manno lineage at the beginning as well as pages 53-57 I think you can infer he is one of the 2. I was guessing he was Liberio's son from the age stated when he got arrested but looking back again its more likely it's his grandson as they all seem to start procreating pretty early.

Their family tree makes me dizzy and without a chart it's tough to write out but using the rule the Rizzuto/Manno/Renda family name their children after their parents and extrapolating down the Lineage of both Nick Sr and his half brother Liberio, I think it works out so that Liberio has a grandson named Calogero Miloto the same as Nick Sr. has a grandson Calogero Renda.

I could be wrong but I think one can say with a degree of confidence that Calogera Miloto is a blood relative of Nick Rizzuto Sr.
