Hi Cyndie:
I was able to find some interesting information about your grandmother's ancestral place.
First, I believe the current location is as follows (Cantonese/Mandarin):
Guangdong Province, Fatshan/Foshan City, Shuntak/Shunde District, Gwun On/Jun'an Town, Choong Moon/Cangmen Neighborhood
廣東省佛山市順德區均安鎮倉門社區
Jun'an is the newer name for Jiangwei (Gong Mei). Jun'an was also the home of Bruce Lee's father. I am not sure that the Ma'ning Village in the Google map is the place for which you are looking. It is in a different town in Shunde District.
I was able to find a whole article about the Ouyang clan of Cangmen, Jun'an on the "Shunde City" website:
www.shundecity.com/view-24940-1.htmlAccording to this article, which includes a photo of the Ouyang Clan temple in Cangmen, the Ouyangs of Cangmen are descendants of the famous Tang Dynasty calligrapher, politician, and writer by the name Ouyang Xun (Wikipedia article:
en.wikipedia.org/wiki/Ouyang_Xun). In fact, that is the whole point of this article. Apparently, there is a genealogy there that can trace clan members back to this person. Warning: the Wikipedia article mentions that Ouyang Xun was so ugly that someone wrote a (satirical) story about him that said he was the son of a general's wife and a "magic white ape"!
Good luck in your genealogical research.
