Are all the immigrants from Rebecca who swept across the north descended from the Ming royal family?

Zongbei is also called "Prince Sweeping the Monument". It seems that the legendary "Rebecca sweeping the north" in Handan area seems to have got Rebecca's permission to sweep the tombstone by mistake.

According to historical records, the mass migration of Hongdong population began as early as the first year of Hongwu (AD 1368). At the end of the Yuan Dynasty, people in the vast areas of the Central Plains were miserable and fled or died one after another due to the chaos of war and chaos and natural and man-made disasters. After the establishment of the Ming Dynasty, Zhu Yuanzhang implemented the strategic decision of "emigrating to settle the fields". However, after the "Jingnan Battle" of the Prince of Yan, people in vast areas of Hebei, Shandong and Henan suffered from wars and natural disasters. According to historical records, "ten villages and nine destroyed, only twelve people remain", especially in Hebei, where there are "green phosphorus and white bones" and desolation everywhere. "Chun Yan is uninhabited and naked for thousands of miles." The Ming government had to set off another wave of immigration. From the first year of Hongwu to the fifteenth year of Yongle, this large-scale activity lasted for fifty years. Many people in southern Hebei have been handed down from generation to generation, and their ancestors moved here from the locust tree in Hongdong County, Shanxi Province. In ancient times, there was a local saying, "Ask where my ancestors came from, Sophora japonica in Hongdong, Shanxi".
