What noble was the ancient Yi surname?

Yi, one of the surnames of China, originated from Hebei, Shanxi Taiyuan and Shandong. It comes from The Shape of the Yellow Emperor Like the Sun and Moon in Historical Records, and its ancestor is Zhongshan Wang Shanggong.

Before the Tang Dynasty, the Yi family tree had disappeared, and there were not many historical records. Only in the Book of Jin, the official history mentioned two generals, Iraq and their biographies. But it moved from Yishui to Taiyuan, Jiyang and then to Jiangdong. Since then, I haven't heard of this easy number, reflecting a few ups and downs.

After the Han dynasty, they settled in Changsha county, and some moved to Jiangxi and eastern Hubei, which has been more than a thousand years. Reproduction continues. In Yichun County in the late Tang Dynasty alone, there were four top scholars, Yi Zhong and Jinshi, which showed its prosperity.
