Jang
A Korean surname, also found as a romanization of some Chinese and other East Asian names.
The #3,890 most common surname in the United States (2010 Census) — about 1 in every 33,835 Americans shares it.
Etymology
Jang is most commonly a Korean surname written 장 in Hangul, usually corresponding to the Hanja 張, a very old East Asian clan name meaning "to stretch" or "to expand." In Korean, it is traditionally rendered as Jang under the Revised Romanization system, though older spellings and alternate romanizations are also seen. The same spelling can also represent unrelated Chinese surnames romanized from different characters, especially in systems that collapse several sounds into "Jang."
History
In Korea, Jang is one of the established clan surnames and is borne by several bon-gwan lineages. In overseas records, the spelling may reflect Korean emigrants as well as immigrants from Chinese-speaking communities whose names were adapted to English orthography in similar ways. Because romanization practices vary, the same Latin spelling can cover more than one family origin.
