One of the most common Filipino surnames is GO. The Filipino-Chinese family name GO is a variant of an old Chinese last name, WU, which also comes in the forms of Gao, the Cantonese Ngo, Ngor, or Gor, Ng, Ang, Eng, and Ing. The family name is traced to the town of Wu Jin of the Jiang Su Province in China and is considered by most experts of Chinese genealogy as the top 10 most common Chinese last name. The word WU means “men of brotherly love”, "god-like" or "the highest."
According to official records, the surname Wu is from any of the following sources: first, that they are descendents of Wu Quan, who was an official of Zhuan Xu (2,513 – 2435 B.C.); second, that they are descendents of Yu Shun (2,255 – 2,205 B.C.); third, that they are descendents of the famous archer of Xia Shao Kang (2,079-2,057 B.C.); and fourth, that they are descendents of the kings of the Wu Kingdom established by Tai Bo and Zhong Yong. Most researchers agree that the last source is the most credible and plausible origin of the family.
