Does anyone know the ancestors of Hejian Sun? Can you tell us something about the development of Sun's surname? thank you

My ancestors were also immigrants from Hong Tong (surnamed Liu);

The migration of Sophora japonica in Hong Tong began in Hongwu period of Ming Dynasty. Our genealogy records Hongwu for two years, and it has been more than 20 generations now, and other surnames in our village have been passed down for about 20 generations.

There is a website about the migration of Sophora japonica in Hong Tong, Shaanxi, which is very detailed. You can search.

The origin of surnames is attached with many associations, so you can't believe it.

The descendants of Sophora japonica have marks on their bodies, and the little toe is a compound toenail, that is, the little toenail is cracked.
