Kwan
A surname most often associated with Chinese names, usually reflecting a character pronounced like Guan/Kwan in different romanization systems.
The #3,966 most common surname in the United States (2010 Census) — about 1 in every 34,439 Americans shares it.
Etymology
Kwan is a romanized surname from Chinese, most commonly representing the surname written 關/关 in traditional or simplified form, or less often other Chinese names rendered with the same spelling in older romanization systems. In modern Mandarin this surname is usually written Guan, while Kwan reflects Cantonese-based romanization, so the spelling mainly preserves pronunciation rather than a separate meaning in English. The underlying character traditionally means a pass, gate, or barrier, and by extension can be a family name with ancient Chinese origins.
History
The spelling Kwan is especially familiar in overseas Chinese communities, particularly among Cantonese speakers and in places influenced by older Hong Kong and southern Chinese romanization. In North America it became a common English-letter form for families whose Chinese surname would now often be spelled Guan in pinyin. Because Chinese surnames are romanized by dialect and system, the same family name may appear as Kwan, Quan, Guan, or related forms in different records.

Fun fact
The same Chinese surname behind Kwan may be spelled very differently depending on whether the family used Mandarin pinyin, Cantonese romanization, or an older local system.
