He was called Siddhartha Gautama in his childhood. His father was king Śuddhodana, leader of the Shakya clan in what was the growing state of Kosala, and his mother was queen Maya. According to Buddhist legends, the baby exhibited the marks of a great man. A prophecy indicated that, if the child stayed at home, he was destined to become a world ruler. If the child left home, however, he would become a universal spiritual leader. To make sure the boy would be a great king and world ruler, his father isolated him in his palace and he was raised by his mother's younger sister, Mahapajapati Gotami, after his mother died just seven days after childbirth. Separated from the world, he later married Yaśodharā (Yaśodharā was the daughter of King Suppabuddha and Amita), and together they had one child: a son named Rāhula. Both Yashodhara and Rāhula later became disciples of Buddha. Suddhodana --Family of Siddartha--wiki
