@ chidorix0x: I do agree with you that it's tales that has been passed down from generation to generation with no known fact until proven, like getting a DNA. Don't get me wrong either. My family and I love to be Hmong. It's just interesting to dig deeper to know where my ancestors came from (now that "Soung" is unknown besides "kong/koo").
My question is, does anybody know their history of their two surnames?
Based on what little (arguably a lot in general) from what I do know (have researched) regarding known and documented historically and to-date scholarships of Hmong surnames (clans) and Chinese-centric surnames,
the "Soung" surname is NOTHING but a re-imagining (late 20th century to 21st century) of "Xyooj"; exactly like "Song". That is pretty obvious. (At least to me, it is!) Take away the "U" and it screams "Song", of which there is no such surname/clan in Hmong, or Chinese, inherently except re-imaginings etc.. (And "NO", the XiongNu, or "Soung" if anyone wants to try and STRETCH it, are not Chinese, per Disney's Mulan animation and factual Chinese historical records. The XiongNu, were in fact, foreign invaders that the Chinese eventually eradicated into extinction 1000s of years ago. True, some XiongNu MIXED-bred descendants may have survived and likely wer assimilated (enslaved) into the Chinese populace -- but not pure XiongNu.)
Let me be frank, blunt, and brutally "honest"; however, do not let this discourage you,
Surikoo2078, or anyone else from researching your root (ancestry) with due diligence. And hopefully your/anyone else's "research" is more grounded in sound scholarships versus hear-say "tales" from parents, grandparents, or even great grandparents -- especially if it (the "tales") cannot be validated whatsoever, as there are a lot of Hmong "tales" of every imagination nowadays. So again, I am of the "belief" that
the "Soung" surname is equivalent to all the RE-IMAGINED Ha'Mung surnames the likes of "Thor, King, Wang/Vaungh, Lord/Lowd, Vu/Wu, Yan, LyFong, BliaLor, Li/Ly, Cha/Chanetc.. And of course "Song", and/or "Soung" too. That is my honest opinion/conclusion -- per my own personal knowledge-base and amateurish scholarly research -- based on both the Hmong community and Western academia. Before all the HA'Mung re-imaginings, the exclusive, better-known (inherent), and more/most popular Hmong surname (clans) are, were, and in fact the 18-Hmong Clan surnames (clans); Xiong, Vang, Yang, Lee, Vue, Lor, Kong, Chang, Kue, Thao etc.. That is fact.
Yes, I know the exact history of both my family surnames (clans); that of my mother and father. Both clan have laid claims to Chinese-ancestry/descendants too. But I know that is just "tales" -- just your basic Hmong affinity with the Chinese.
