Did the Hata clan come from the Qin?

　　　　Furthermore, a history of ancient China describes that Shin-kan was founded by the people who had escaped safely from the Qin, which has been inscribed “秦” in a Chinese character, when their homeland had ruined in B.C. 206. Shinsen-Syousi-Roku also described that in the reign of Chuuai Tennou, in the 2nd century, a precedent group of the Hata clan had come to Japan lead by a person who was descended from king Koubu, whose grandfather was the First Emperor of the Qin dynasty. His name was Okuma, or Kuma. He might have been a grandfather of Yuzuki-no-kimi, and at one time he by himself or his father might have gone over to Kudara. If so, would the Hata clan have been the people of the ancient China, Qin?
