You’ve traced your lineage to Huang Di (the yellow emperor 皇帝)

From the point of view of the genealogical research, this (Guangdong) history also provides some guidance for evaluating information on one’s ancestral tree. Although it is probably true that the remote ancestors of many Guangdongese can be traced to North China and perhaps even to the Yellow Emperor, another fact, obvious from Guangdong history, is that the native Yue and their heirs once formed a significant part of the Guangdong population and have left an obvious physical and cultural imprint on the (Cantonese) people. Yet, one finds very few Guangdongese claiming them as ancestors. One suspects, however, they may have more descendents in Guangdong than is generally acknowledged in the genealogies, since many Guangdong genealogist, in seeking social status and prestigious and respectable ancestral trees, may have been tempted to make claims, often unsubstantiated, to remote ancestors of northern, and hence Han Chinese, as opposed to “southern barbarian” origin. It should be noted that women, at least some of whom were not of northern Han Chinese origin, are excluded from genealogical considerations when tracing lineages. Also over the centuries there have been numerous changes of surnames for various reasons so that the possession of a certain surname does not necessarily ensure descent from the alleged progenitor of that clan. All these considerations point to the fact that it is not an easy task to do historically rigorous genealogical research. A few family have a reliable genealogy reaching back many centuries. For example the genealogy of the descendants of Confucius is probably one of the few authentic ones since so much attention had been focused on the family during the entire course of Chinese history. For others the historically reliable part would not extend beyond the progenitor of the local lineage identified with his clan village of origin. In still other cases, the situation falls somewhere between the two extremes. In all cases, including the genealogy of Confucius’ family, a point is eventually reached beyond which the information is not subject to rigorous historical analysis and can only be considered part of a tradition. Tradition, as long as one recognizes the limitations, of course can continue to be a source of pride and strength in the particular individual and his family. (emphasis my own)
