My surname is Wen Manchu with white flag, and my ancestral home is Acheng, Heilongjiang. What's my Manchu surname?

You'd better go back to your hometown to consult the genealogy, which is the most accurate record.

The Eight Banners have nothing to do with surnames.

Your surname may be "given name", that is, the word "smell" is in the name of a certain generation of ancestors in this family, and future generations will take this word as their surname.

Furthermore, Manchu people take the transliteration of Wen's surname, and the old surname is.

But this situation is relatively rare.

Some Manchu people in Acheng, Heilongjiang Province were the "Beijing flags" that moved from Beijing to their hometown in Northeast China during the reign of Kang Gan in Qing Dynasty. Others were transferred from Ning 'an or Jilin to the local garrison in the Qing Dynasty.
