There is a Roche genealogy in Bayan Village, Guandao Town, Tongcheng County, which was rebuilt on 199 1. It records the history from the Yongle period of the Ming Dynasty (I don't remember clearly, I don't know if it was the Yongle period, but it was the Ming Dynasty. ) from 199 1, a part of the descendants of Roche in Tongcheng, ***24 generations, with 80 words of generational poems. From 2 1 to 25 generations, they are: Heng, Yun, Hui, Shi and Lai. According to the above records, this genealogy was recorded in the Song Dynasty, but I don't know why it didn't exist from the Song Dynasty to the Ming Dynasty. I don't know if it is what you want.
