The surname BAHNG has its origins in the Korean peninsula, tracing back to the 14th century during the Goryeo dynasty. It is believed to be derived from the Korean word "bang," which means "room" or "chamber," suggesting that the name may have originated from a family or clan associated with a particular dwelling or residence.
One of the earliest recorded instances of the name BAHNG can be found in the Annals of the Goryeo Dynasty, where a scholar named BAHNG Jiwon (1287-1367) is mentioned. He served as a high-ranking official and played a crucial role in the transition of power from the Goryeo to the Joseon dynasty.

In the 18th century, BAHNG Yeongsam (1720-1798) was a respected military commander and strategist who played a pivotal role in defending the Korean peninsula against Japanese invasions. His military tactics and leadership during the conflicts have been documented in historical records.
Another significant figure from the BAHNG family was BAHNG Hakgi (1768-1831), a renowned calligrapher and artist. His calligraphic works are considered masterpieces and have been preserved in various museums and collections.
The BAHNG surname has also been associated with various place names throughout Korean history. For example, the village of Bangchon, located in Gyeonggi Province, is believed to have derived its name from the BAHNG clan that settled in the area.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
