Alto Piccolo is the only son of Piccolo, thus making him grandson to King Piccolo/Kami. His Japanese name, アルトピッコロ, literally corresponds to Alto Piccolo. To distinct between himself and his father, he is almost always called Alto. He only uses the name Piccolo, as a surname on Earth. Piccolo never meant to reproduce, even saying it was "Disgusting, and horrifying experience", he was asked to by the Grand Elder Guru to save the race of Namekians from going extinct.
