Origin
Meaning and origin of Boriboun
The surname BORIBOUN has its origins in Thailand, where it first emerged in the late 16th century. It is believed to be derived from the Thai words "bori," meaning "border" or "boundary," and "boun," meaning "village" or "settlement." This suggests that the name may have originated from a border village or settlement located along the boundaries of Thailand.
One of the earliest recorded instances of the name BORIBOUN can be found in a historical manuscript from the Ayutthaya Kingdom, which ruled over much of modern-day Thailand from the 14th to the 18th centuries. The manuscript, dated to the early 17th century, mentions a village called "Boriboun" located near the Khmer border in what is now eastern Thailand.
In the 18th century, a prominent figure named Luang Boriboun served as a high-ranking official in the royal court of King Rama I, the founder of the Chakri Dynasty that still reigns over Thailand today. Luang Boriboun was instrumental in establishing trade agreements and diplomatic relations with neighboring kingdoms.
Another notable individual with the surname BORIBOUN was Chao Boriboun, a 19th-century nobleman and military leader who played a crucial role in defending the kingdom against Burmese invasions. His bravery and strategic prowess earned him a place in Thai history books.
In the late 19th century, a Buddhist monk named Phra Boriboun Siddhi gained recognition for his teachings and contributions to the preservation of Thai culture and traditions. His writings and sermons were widely circulated and influential during that time.
During the early 20th century, a prominent artist and sculptor named Srithat Boriboun made significant contributions to the Thai art scene. His works, which often depicted traditional Thai life and culture, can be found in various museums and galleries throughout the country.
While the surname BORIBOUN is not as common as some other Thai surnames, it has a rich historical legacy that spans several centuries and encompasses various fields, from government and military to religion and the arts.

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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers.
