Leonardo Graviossi, one of the most successful mob bosses in this area. His parents gave him a mansion and their money after their deaths, which only gave him a good start to becoming the biggest mob boss. Dealing drugs, killing off dealers who mess with him, many many of his men and maids at home doing as they're being told.
Leonardo has a wife, Carmella, their marriage wasn't out of love, but a way to "cover Graviossi's family mistake" made years ago, when they killed all of the sons of the family Carmella was from. There's no "real love" between Leonardo and Carmella, only mutual respect and the need to have the family name, "Graviossi", going.
And they managed to get it going, on their first try for a baby, Carmella got pregnant and gave birth to Leonardo's first son, Rosario.
