Guan
A surname found in several cultures, most commonly a romanization of Chinese family names with meanings that depend on the specific character.
The #4,867 most common surname in the United States (2010 Census) — about 1 in every 42,603 Americans shares it.
Etymology
In Chinese, Guan is usually a romanization of one of several different surnames written with different characters, so the meaning depends on the family line and character used. Common possibilities include 關/关, meaning a fortification or pass, and 管, meaning a tube, pipe, or to manage; other rare Chinese surnames can also be rendered Guan in romanization. In non-Chinese contexts, Guan can occasionally arise as a variant spelling or altered form of surnames in other languages, but those cases are much less common in modern English-speaking records.
History
In the United States today, Guan is most often encountered as a Chinese surname brought by immigrants and their descendants, especially through pinyin or other modern romanization systems. Because several distinct Chinese surnames can be written the same way in Latin letters, one cannot safely assign a single origin story without knowing the original Chinese character. Older English-language records may also flatten different pronunciations and spellings into the same form.

Fun fact
A single Roman-letter surname like Guan can conceal multiple unrelated Chinese surnames, so two people named Guan may have entirely different family histories.
