수원 백씨(水原 白氏) — The Suwon Baek clan (水原 白氏), with its ancestral seat in today's Suwon, Gyeonggi Province, is by far the largest Baek seat, with 354,428 people in the 2015 census. Its founder is said to be Baek U-gyeong, who crossed from Tang China to Silla. Several other Baek seats were folded into Suwon from the 1980s-90s with the compilation of a joint genealogy, enlarging it further.

In the 2015 Census the 수원 백씨 clan numbered about 354,428 people, one of Korea's major surnames and clans. Even among people surnamed 백, a different clan seat (bon-gwan, 수원) means a different lineage.

The Suwon Baek clan (水原 白氏) is the leading seat of the Baek (白) surname, with its ancestral seat in Suwon, Gyeonggi Province. In genealogical tradition the founder is Baek U-gyeong (白宇經). According to the Baek daedongbo he came from Suzhou, China, served the Tang court, and crossed to Silla in 780 (the first year of King Seondeok) and settled beneath Mt. Jaoksan. Explanations from the Korean Language Society repeat this while noting that no ancestor before him can be identified, and other accounts place him in the reign of King Gyeongdeok, so the date differs by source.
The middle progenitor is Baek Chang-jik (白昌稷), said to have been a captain under King Gyeongmyeong of Silla and posthumously made a general; descendants count generations from him as the first. The generations between Baek U-gyeong and Baek Chang-jik, and the lineage after him, are not clearly documented, and the deeds of figures such as Baek Hwi and Baek Cheon-jang cannot be confirmed. The Sejong sillok jiriji (1454) records the Suwon Baek as having come from Gaeseong, and the first person known to write 'Suwon' as his seat is Baek Hyo-sam on his 1427 examination record.
The theory that the founder came from Tang China rests on a 1669 account based on the 1637 Jeongchuk old genealogy of the Daeheung Baek and has been criticized as lacking firm documentation. Some raise the possibility that the Baek (苩) of Baekje's eight great families became the present Baek (白) in Unified Silla, but how the two connect is unknown. This text therefore treats such stories as tradition, not fact.
The Baek surname ranks 28th in Korea with 381,986 people in the 2015 census, and the Suwon seat is said to make up about 90%. Much of this results from the 1980s-90s, when a joint clan assembly unified the seat as Suwon, claiming it as the senior line, and published a joint genealogy. According to Korean Wikipedia, some branches became independent seats: the Osangun line as Cheongdo Baek, Damam-gong as Jiksan Baek, Jeongsinjae-gong as Haemi Baek, Buyeo-gun as Buyeo Baek and Mungan-gong as Nampo Baek.
However, some older seats such as Nampo, Jiksan, Daeheung, Sangdang, Daegu, Gimcheon, Pyeongsan and Jeokseong objected that the Suwon genealogy was unclear, and there is criticism that several seats were recently merged without clear evidence. The 1997 reissue of the Suwon Baek daedongbo is said to have used Chinese genealogies, and a story says Korea's 1982 Baek daedongbo was used to supplement a Chinese genealogy. Depending on how the seat is viewed, the same person may appear under Suwon or another seat, so please check your own genealogy.
In late Goryeo, the Grand Academician Baek Jang (founder of the Jeongsinjae-gong branch), a disciple of Jeong Mong-ju, declined office after the founding of Joseon and ended his life in exile in Jangsu, while Baek In-gwan (Seonjeong) is said to have taken his parents back to Suwon and ignored King Taejong's summons. Such stories of loyalty recur across several branches.
The clan rose to prominence under the Suwon seat with Baek In-geol (1497-1579) in mid-Joseon. A disciple of Jo Gwang-jo and teacher of Yi I and Seong Hon, he served as Chief Censor, Inspector-General and Vice Minister of Works, was named an incorruptible official, and received the posthumous name Mungyeong. His elder brother Baek In-yeong was a Royal Secretary, and the brothers and cousins were known as the 'four Baek men of letters'. In the Gichuk purge Baek Yu-yang and his sons were beaten to death, but the descendants of Baek In-geol flourished and are said to form a majority of the clan today. Korean Wikipedia lists civil examination graduates including Baek Hyo-sam, Baek Sa-su, Baek In-yeong, Baek In-geol, Baek Yu-yang and Baek Yu-ham, plus 101 military graduates, 54 saengwon and 57 jinsa (partial records).
In late Joseon the secondary-son warrior Baek Dong-su helped compile the Muyedobotongji with Yi Deok-mu and Pak Je-ga. Baek Gwang-hyeon, the royal physician under Sukjong, is introduced as belonging to the Imcheon Baek, a branch of the Suwon Baek; Korean Wikipedia lists his seat as Imcheon.
The modern era brought great variety. In the independence movement there are Baek Yong-seong, one of the 33 national representatives; Baek Jeong-gi of the Rokusantei plot; and Baek Gwan-su, who read the February 8 Declaration. In scholarship and education: Baek Nak-jun, first president of Yonsei University; the socio-economic historian Baek Nam-un; and the surgeon and Baek Hospital founder Baek In-je. In government, Baek Du-jin served as prime minister and Speaker. The soldier Paik Sun-yup is assessed differently because both his Korean War record and his service in the Gando Special Force are discussed. In the arts, Nam June Paik became known worldwide as the founder of video art.
The Suwon Baek are introduced as divided into dozens of branches, including Sirang-gong, Yanggok-gong, Taesa-gong, Buyeo-gun, Mungan-gong, Dongnim-gong, Damam-gong, Seonjeong-gong, Bongikdaebu-gong, Jeongsinjae-gong, Busa-gong, Geumneungbuwongun, Inju-gong, Osangun, Jangdan-gong, Cheongsan-gong, Sa'eum-gong, Impi-gong, Jwarang-gong, Hunjeong-gong, Doseungji-gong, Chambong-gong, Byeoljwa-gong, Mungyeong-gong, Jungnangjang-gong, Hampan-gong and Jeolje-gong (some became separate seats). The Seonjeong-gong, Inju-gong, Osangun, Damam-gong, Mungyeong-gong and Jeongsinjae-gong branches are described in detail in the branch cards below. Lineage and generation names may differ by branch, so confirm your own branch in the genealogy.
Clan villages are introduced in places such as Imnam-myeon in Gimhwa and Mokjeon-myeon in Pyeonggang (Gangwon); Seojong-myeon, Yangpyeong (Gyeonggi); Gyochon-ri in Noseong-myeon, Nonsan, Jangam-myeon in Buyeo and Sicho-myeon in Seocheon (South Chungcheong); Jinan, Impi-myeon in Gunsan, Gochang and Goksan-myeon in Wanju (North Jeolla); Mu'an, Yeongam, Hwayang-myeon in Yeosu and Jangheung (South Jeolla); Geochang and Goseong (South Gyeongsang); and Yecheon, Yeongdeok and Gyeongju (North Gyeongsang). Villages also existed in Hwanghae and the Pyongan provinces. The Baek share is somewhat higher in Daegu, southwestern North Gyeongsang and the South Jeolla coast (Jangheung, Yeosu, Suncheon).
The common generation-name scheme is said to run from the 23rd to the 46th generation counted from the middle progenitor; the examples given on Korean Wikipedia are 師 (23rd), 東 (24th), 鎭 (25th), 洙 (26th), 樂 (27th) and 南 (28th). The remaining characters and branch-specific schemes could not be confirmed and may differ by branch, so compare with your own genealogy.
Clan affairs are handled by the Suwon Baek Central Clan Association, whose website is http://www.suwonbaek.org (a security-certificate warning may appear and we could not verify it directly). Korean Wikipedia also lists a Suwon Baek Daejonghoe, but whether it still operates could not be confirmed. The Jeongsinjae-gong branch has its own association, the Suwon Baek Jeongsinjae-gong Daejonghoe.
Branches, lineages and seat labels may differ by clan, genealogy and source, so confirm with your own genealogy.
Seonjeong-gong-pa, Inju-gong-pa, Osangun-pa, Damam-gong-pa, Mungyeong-gong-pa, Jeongsinjae-gong-pa
The Seonjeong-gong branch descends from Baek In-gwan (白仁寬), pen name Seonjeong (禪亭), a figure of late Goryeo. When the late-Goryeo court fell into disorder he withdrew from office and took his parents back to the clan seat of Suwon, and after the founding of Joseon he is said to have refused King Taejong's repeated summons. This story of loyalty is typical of several Suwon Baek branches whose founders lived in late Goryeo, such as Jeongsinjae-gong.
He is said to have later settled in Nogok-dong, Daegu, becoming the first Suwon Baek ancestor there, and Hwaam Seowon in Daegu is said to have been founded to honor his loyalty. Daegu and southwestern North Gyeongsang are areas where the Baek share is relatively high, which fits the traces of this line's descendants living around Daegu.
In the clan's branch chart the Inju-gong branch and others are placed under the line of Baek In-gwan. However, the founder's exact dates, offices, posthumous name and lineage could not be confirmed, nor could the current state of clan villages, shrines or associations. Please check with your own genealogy and clan association whether your family belongs to this branch.
The Inju-gong branch is a Suwon Baek line descended from Baek Yeok (白繹). In the clan's branch chart it is placed under the line of Baek In-gwan, founder of the Seonjeong-gong branch. 'Inju' (仁州) is known as the Goryeo-era name for the Incheon area, so the branch name may relate to the founder's title or home, but no confirming record was found.
Korean Wikipedia lists the Suwon Baek as divided into dozens of branches such as Sirang-gong, Yanggok-gong and Taesa-gong; Inju-gong is among the branches named alongside Seonjeong-gong. As Seonjeong-gong is known through stories of late-Goryeo withdrawal and loyalty, Inju-gong can likewise be understood as a branch of the family from that period.
The founder Baek Yeok's life and offices, and this branch's lineage, settlements, generation names and association could not be supplemented because little accessible material exists. If you descend from this branch, please check the precise branch lineage through your genealogy or the Suwon Baek Central Clan Association.
The Osangun branch is a line of the Suwon Baek clan; some sources record Baek Yang-sin (白良臣) as its founder and link this line to the Cheongdo Baek clan, and Korean Wikipedia likewise explains that Osangun separated and continued as the Cheongdo Baek. It is thus a branch presented both as a limb of the Suwon Baek and as the root of another seat, Cheongdo.
The name 'Osangun' (鰲山君) looks like a Goryeo-style title of nobility, but how the founder received it could not be confirmed. This is one of the debates left over from the merging of Baek seats under Suwon, linked to the objections raised by some older seats that the Suwon genealogy was unclear.
Cheongdo lies near southwestern North Gyeongsang, where the Baek share is relatively high, so this line may connect with settlement there, but its specific villages, descendants, generation names and association could not be confirmed. Whether a family writes Suwon or Cheongdo as its seat can differ, so check your own genealogy first.
The Damam-gong branch descends from Baek Mun-bo (白文寶, 1303-1374), pen name Damam (淡庵), a late-Goryeo official and Neo-Confucian scholar. He served as minister of personnel (jeolli panseo) and royal adviser, lectured at King Gongmin's royal study sessions, and in 1363 proposed spreading the use of waterwheels. He is counted among the Baek figures in the Goryeosa biographies.
His collected works, the Damam iljip, survive. The Encyclopedia of Korean Culture and other references give his clan seat as Jiksan (稷山), and Korean Wikipedia explains that Damam-gong separated and continued as the Jiksan Baek. He is therefore presented both as a branch founder of the Suwon Baek and as a leading figure of the Jiksan Baek, depending on source and clan.
In the introduction of Suwon Baek figures, Baek Mun-bo is not asserted to be Suwon Baek directly but is named only as the founder of the Damam-gong line. The branch's lineage, settlements, generation names and association could not be confirmed. If you descend from it, first check whether your genealogy writes Suwon or Jiksan as the seat.
The Mungyeong-gong branch descends from Baek In-geol (白仁傑, 1497-1579), pen name Hyuam (休菴), a mid-Joseon official. A Sarim disciple of Jo Gwang-jo, Kim An-guk and Kim Sik, he passed the civil examination in 1537 and is known as a teacher of Yi I and Seong Hon. He was dismissed for criticizing the Queen Dowager's regency and in 1547 was implicated in the Jeongmi purge and exiled to Anbyeon.
He returned late in Myeongjong's reign to serve as Chief Censor, Inspector-General and Vice Minister of Works, was posthumously named left associate state councillor and listed as an incorruptible official. His posthumous name was first Chungsuk (忠肅), then changed to Mungyeong (文敬), which gives the branch its name. He is enshrined at Bongsan Seowon in Nampyeong and Pasan Seowon in Paju; his tomb in Hyochon-ri, Gwangjeok-myeon, Yangju, is Gyeonggi Provincial Monument No. 58. The Hyuam seonsaeng silgi survives.
The descendants of his sons Baek Yu-gong, Baek Yu-hang and Baek Yu-ham flourished and are said to be a majority of the Suwon Baek. About 80 Suwon Baek households live in Maegok-ri, Gwangjeok-myeon, Yangju, where the Baek Su-hyeon house remains. The activists Baek Jeong-gi and Baek Gwan-su are said to be descendants. The branch of individual descendants differs by genealogy and is not asserted, and the branch's generation names and association could not be confirmed.
The Jeongsinjae-gong branch descends from Baek Jang (白莊, 1342-1418), pen name Jeongsinjae, a Grand Academician of late Goryeo. He studied under Jeong Mong-ju and is remembered as a Neo-Confucian scholar comparable to the 'Three Eun'; after the founding of Joseon he withdrew to Mt. Chiaksan to organize Neo-Confucian learning and teach disciples. King Taejo and King Taejong repeatedly asked him to take office, but he refused, and he is said to have been exiled to Jangsu in Jeolla, where he died in 1418.
Jangsu County honors him with Hwang Hui as one of its two 'virtues', and his memorial tablet is kept at Wolgangsa in Janggye-myeon. On July 9, 2026 the Suwon Baek Jeongsinjae-gong Daejonghoe unveiled a 2 m bronze statue at Cheongsim Park in Jangsu-eup (150 million won), and a separate 'Baek Jang Ancestral Site Restoration Project' (July-December 2025) replaced the Sungui-je roof and repaired earthen walls.
Korean Wikipedia explains that Jeongsinjae-gong separated and continued as the Haemi Baek, but the clan uses the name Suwon Baek Jeongsinjae-gong Daejonghoe, so the seat label differs by source. The branch's lineage, generation names and settlements could not be confirmed, so please check with the association and your genealogy.
Branch divisions vary by lineage and jokbo; confirm your own branch in your family's records.

The Suwon Baek clan (水原 白氏) has its ancestral seat in Suwon, Gyeonggi Province. Its founder is Baek U-gyeong (白宇經), said to have come from Tang China to Silla, and the middle progenitor is Baek Chang-jik (白昌稷). As the leading seat of the Baek surname it is said to have given rise to the Cheongdo, Jiksan, Haemi, Buyeo and Nampo Baek, among others (some of these merges are disputed).
They include the incorruptible Joseon scholar Baek In-geol, the warrior Baek Dong-su, the national representative Baek Yong-seong, and the activists Baek Jeong-gi and Baek Gwan-su. In modern times there are Baek Nak-jun, first president of Yonsei University; the economist Baek Nam-un; the surgeon Baek In-je; Prime Minister Baek Du-jin; the soldier Paik Sun-yup; and Nam June Paik, founder of video art. The late-Goryeo Grand Academician Baek Jang founded the Jeongsinjae-gong branch.
The detailed branch and lineage divisions vary by clan and genealogy, so confirm your own family's history in the genealogy you hold.
