King Zhaoxiang of Qin
Because King Zhaoxiang had not yet legally come of age (traditionally at the age of 20), his mother, who was now known as Queen Dowager Xuan, became the regent. She was supported by her brothers, Wei Ran and Mi Rong (羋戎), as well as two other sons, Prince Yi (公子悝) and Prince Fu (公子巿), the four of them collectively known as the "Four Nobles" (四貴).
Duke Ling of Qi
Duke Ling also had another son named Chujiu, born to another of Duke Ling's concubines, who was the daughter of Shusun Xuanbo, leader of the Shusun clan of Lu. Cui Zhu would later kill Duke Zhuang and install Chujiu on the throne, to be known as Duke Jing of Qi.
