Between Two Seo Clans: Considering a Song Family Link to Philip Jaisohn

Guest post by Sieon Lim1

Recently, one of our student workers, Sieon Lim, conducted research on Thomas Gregory Song’s mother, Seo Jeong-ah, and her family lineage and bongwan (clan). The following is a condensed summary of his findings regarding Seo Jeong-ah and the potential for her (and by extension, her family) to share a bongwan with the prominent Korean/Korean American reformer and activist Philip Jaisohn (born Seo Jae-pil, 1864–1951).

The Dalseong Seo clan holds a particularly significant place among the prominent Seo lineages in Korea; over time, a branch of the clan became more prominent in Korea’s capital and began maintaining its own separate genealogical records. Although members of this branch continued to recognize their shared kinship with the Dalseong lineage, the branch came to identify Daegu as its bongwan.2 

Crests of the Daegu and Dalseong Seo Clans

In 1884, two Daegu Seo clansmen, Seo Jae-pil and Seo Gwang-beom, played leading roles in an attempted coup d’état against the Joseon court, known today as the Gapsin Coup (also spelled Kapsin Coup). The coup failed, leading to the punishment and persecution of its organizers and their families. In order to distance themselves from those who had taken part in the revolt, the Daegu Seo clan altered its generation naming conventions (hangnyeolja).

According to traditional Korean naming conventions, names are generally composed of a surname and a given name, which is made up of a generational name and a unique name. Each clan has its own set of generational names, which are assigned based not on when a person was born, but rather on their place in the lineage (meaning two people from different time periods can end up in the same generation and thus have the same generational name). 

For the Daegu Seo clan, the 25th generation name was “Gwang” and the 26th was “Jae.” However, following the attempted coup, the clan altered its naming convention, introducing “Byeong” and “Jeong” in place of “Gwang” and “Jae,” respectively.3 This meant that going forward, all members of the 25th generation were named using the generation name “Byeong,” and all members of the 26th generation were named using the generation name “Jeong.” 

Three genealogical trees color-coded by family

Comparison of 25th- and 26th-generation naming patterns across three Seo family lineages: Lim’s family (blue), Seo Jae-pil’s lineage (yellow), and Seo Jeong-ah’s lineage (green). The diagram highlights the use of the generational names Gwang/Jae and Byeong/Jeong discussed above.

For Thomas Song’s mother, Seo Jeong-ah, her name was constructed using the generation name “Jeong.” Furthermore, her father, Seo Byeong-gi, used the generation name “Byeong,” which also corresponds with the name change found in the Daegu Seo naming convention. While this could be a coincidence, the pattern appears to align closely with the Daegu Seo clan, suggesting the likelihood that Seo Jeong-ah and her family were members of the smaller Daegu Seo clan, as opposed to the Dalseong Seo clan. 

Today, the Dalseong Seo clan vastly outnumbers the Daegu Seo clan. For members of the Daegu Seo clan, explaining membership in a lesser-known branch can require far more effort than simply identifying with the better-known lineage, particularly given the historical relationship between the two. Thus, some members of the smaller Daegu Seo clan may identify themselves as belonging to the larger Dalseong Seo clan. Over generations, this practice may also make it more difficult for descendants to recognize their connection to the smaller Daegu Seo clan, particularly in families that migrated away from Korea.

Amidst the fallout of the Gapsin Coup, Seo Jae-pil moved to the United States, where he adopted the name Philip Jaisohn and became the first Korean to gain naturalized American citizenship. He later earned his medical degree, becoming the first Korean to do so in the United States. Given this trajectory, we can find parallels between Jaisohn’s life and that of Seo Jeong-ah, who eventually became one of the first female Korean doctors to earn a medical license in Imperial Japan.

A genealogical family tree

In regard to the Song Family Collection, these findings are not about claiming historical prestige, but rather about illustrating the complexity of Korean genealogical research and the care required when seeking to identify and interpret clan affiliations. They also underscore a broader theme that is present throughout the Song Family Papers: how lives, identities, and family records are shaped by imperialism, war, displacement, and historical rupture. 

Notes:

1. Student author Lim’s interest in this question was partly personal: his own family traces its lineage to the Daegu Seo clan, and he was intrigued by the possibility of a genealogical connection to Thomas Song’s family. His research was also informed by his family’s longstanding understanding that they belonged to the Dalseong Seo clan. This unexpected intersection between his own family history and the Korean family represented in the Song Family Collection inspired Lim to pursue summer work as a student researcher at The Ohio State University, adding a particularly personal dimension to this research.↩

2. The historical relationship between the Dalseong Seo and Daegu Seo clans is complex. The Daegu Seo were associated with the Gyeongpa (京派, “capital branch”) and the Dalseong Seo with the Hyangpa (鄕派, “local/provincial branch”). Although the two groups recognized one another as kin, Daegu Seo genealogies increasingly distinguished between them. According to Yu Su-ji, the first Daegu Seo genealogy, compiled in 1702, recorded the Dalseong Seo separately in a supplementary genealogy; subsequent genealogies continued to negotiate the relationship between the two groups.

A Remarkable Family Calligraphy Book

Guest Post by Max Li

In early March (2025), we opened the exhibit “Mobility, Collecting, and Diaspora: Preserving and Teaching East Asian History” in the Special Collections Atrium of the main campus library. Drawing on rare and distinctive works from multiple campus collections—including the Thompson Libraries’ Special Collections and the Bliss M. and Mildred A. Wiant Collection of Chinese Art—the exhibit celebrates the depth and diversity of East Asian materials at OSU. 

Among the featured items, one artifact stands out: a well-preserved calligraphy book that contains Chinese poems and inscriptions from Korean monuments.

A treasured family heirloom, the book has journeyed across borders and generations—traveling from Korea to Japan, northeast China, back to Korea, and ultimately to the United States. Preserved for centuries by the ancestors of Thomas Gregory Song’s mother,  So Jong-Ah (1905–1995), the volume now resides in the Rare Books & Manuscripts Library at University Libraries. Its remarkable journey truly captures the exhibit’s central themes of mobility, collecting, and diaspora.

Created in 1740, the book contains ink rubbings of calligraphic inscriptions originally carved on one of two stone stele that are part of the Historic Monuments and Sites of Kaesong, a UNESCO World Heritage Site in present-day North Korea. The calligraphy was drawn by the reigning monarch at the time, King Yeongjo (r. 1724–1776), the 21st ruler of the Joseon dynasty. Scholars believe that the rubbings are roughly contemporary with the original stele: their precision and clarity suggest they were made immediately, before the stone inscriptions were weathered by time. 

Produced by royal hand, such calligraphy rubbings served as exemplary models for students learning to write—a vital skill in the East Asian scholarly tradition, where penmanship was linked to reputation and status. Creating these rubbings required meticulous craftsmanship. After pasting a traced copy of the original calligraphy onto the stone, engravers would carefully carve through the outline, striving for exact replication. 

“Stowaway Poems” and Recycled Paper

Interestingly, the rubbings in this book were printed on the reverse sides of reused paper—sheets that had been inscribed previously with poetry, likely at a much earlier date. In traditional China, it was not uncommon for new texts to be printed on the backs of both public and private discarded papers. Following a consult with Chinese Studies Librarian, Professor Guoqing Li, we know that the hidden texts on the back of these pages include poems by the renowned Tang dynasty poet Li Bai (李白, 701–762), also known as Li Bo, courtesy name Taibai (太白). Widely celebrated as one of China’s greatest poets, Li Bai’s “stowaway” verses add another layer of significance to this already remarkable manuscript.

Beyond the Page

The donation of the Song Family “calligraphy book” builds on the important historic materials already held in that collection. This is an exceedingly rare artifact that presents great potential for research in Chinese literature and book technologies, as well as Korean history and calligraphy. It not only contains important stone monument rubbings from a world heritage site in North Korea, but also provides a rare example of ancient “paper recycling.” The inverse sides of the pages in this calligraphy book contain Tang-period “stowaway” poems that were written on the paper at an earlier (unknown) date, prior to 1740. The calligraphy book is a precious and unique resource that bridges history, literacy, and transnational heritage, underscoring the Song family’s deep respect for both tradition and knowledge.

The Frog Outside the Well

The Jokbo Challenge

One of the most important items in the Song Family Collection is the Eunjin Song Clan jokbo. For the uninitiated, jokbo1 are traditional Korean genealogies detailing family lines going back to their first common ancestor. There are many types of jokbo, and they have certainly evolved over time, but the Eunjin Song Clan jokbo is a patrilineal record typical of the Confucian-based Joseon period society.

For our purposes, in tracing the history of the Song family diaspora in the modern era, the Song Family jokbo has been an indispensable resource. Above all, we have used it to confirm birthdates and Chinese characters in the names of the various members of the latest generation of the Song family. However, making sense of the family jokbo has been no easy matter. To better utilize Korean jokbo as a tool for such genealogical research, I searched Google for any credible English-language information on the topic. Luckily for me, I found a gold mine.

Enter Professor Mark Peterson

While hunting for resources, I discovered a master of the craft: Professor Emeritus of Korean, Asian, and Near Eastern Languages at Brigham Young University, Dr. Mark Peterson, an expert on Korean language and history and an impassioned translator of jokbo. On his YouTube channel, “우물 밖의 개구리The Frog Outside the Well,” Dr. Peterson has curated a playlist of seven instructional videos in which he covers the key elements for understanding a jokbo. After viewing these videos, I was able to get a solid start on reading the Song family jokbo.

Peterson’s videos can be divided into roughly two sections. The first is with a woman named Jiwon “Rebecca” Moon, who brings her genealogy to discuss with Dr. Peterson in the video. They explain, over three videos, the five important Chinese characters needed to read jokbo, the changes in jokbo over time, and a “special” kind of jokbo known as a palgojodo (팔조조도) or “eight great great grandfather chart.”

The second section is another series of three videos with a 3rd generation Korean-American named Braden Oh, who contacted Dr. Peterson for help investigating some of his own family jokbo. Notably, Oh was seeking Peterson’s support due to his inability to read Korean. Together these videos cover basic information on immediate family and relationships, basic biography and burial information, and how to trace ancestry up from the present generation to the more recent generations.

A seventh and final video stands on its own: a lecture in Korean by Dr. Peterson talking about the relationships of Koreans with jokbo, and how to solve the “jokbo problem” (i.e. some people love them and some hate them). This video goes into great detail about the palgojodo, which traces both female and male ancestral lines (rather than focusing solely on paternal lines).

Everyone Can Read Jokbo!

Before engaging with Dr. Peterson’s videos, I had no understanding of how to navigate a jokbo. Though I was able to use my knowledge of Chinese characters to crudely navigate through its pages, the “flow” of the system and the quirks in its character choices eluded me. For example, I had no way of knowing that “卒”, which (in Japanese, at least) means “graduation,” actually denotes a person’s death date. Thanks to Dr. Peterson’s content, I am much more confident navigating a variety of old and new jokbo.

If you have any interest in learning about jokbo, no matter your language or ancestry, I encourage you to take a look at his content and explore some jokbo on your own. It is a fascinating type of archival record with a rich history, and one certainly worth your time.

Jokbo Translation

This week the talented researcher, Evie Seitz, has been translating a couple of pages (pp. 268-69) from the Song family Jokbo held in OSU’s Rare Books & Manuscripts Library. The significance of these specific pages is that they list the names of immediate family members in Thomas Song’s generation (Generation #26), his father’s generation (Generation #25), and his grandfather’s (Generation #24). Evie’s work on this translation is so important that I’m posting it below for future access:


Song Family Jokbo Translation Explanation

by Evelyn Seitz

July 21, 2023

The sister document to this (“Final Jokbo Translation”) is an Excel spreadsheet holding a faithful translation of pages 268 and 269 of the Eunjin Song clan jokbo. In order to better understand the format of both the original and the translation, brief explanatory notes are provided below.

In the Eunjin Song clan jokbo, only the names of sons are recorded. Sons are noted with the character 子 (Hangeul: 자; RR: ja; “child”) followed by their name. Daughters are listed with the character 女 (Hangeul: 여; RR: yeo; “woman”) followed by their husband’s name. The exception to this rule is that starting with the 27th generation, daughters are noted 女 followed by their own names; married daughters are listed in the same manner, with the addition of their husband noted by 夫 (H: 부; RR: bu; “husband”) and the husbands name, written immediately to the left with a small space (smaller than between siblings in a row).

Jokbo are read in a “stair step” method, moving from top-to-bottom, right-to-left. Each row is a generation, with the oldest at the top and the most recent at the bottom. Starting at an upper row, names listed directly below and to the left of any given son are his children, until there is a gap, and one travels back up the page to another upper row to follow a new line down. Below is a photo of the original, untranslated pages, annotated to show the flow of reading:

I have opted to translate only the most relevant relations to Thomas and Albert Song on this page. As such, only the 23rd, 24th, and 25th generation lines on pages 268-269 have been translated. As of July 20th, 2023, several small sections have been left untranslated, as consultation with outside specialists may be necessary to accurately parse them. For now, they have been left in Chinese characters as red or blue colored text to mark them for future inquiry.

The translation spreadsheet is formatted such that it follows the same method of reading as the jokbo, simply reversed to accommodate English reading direction. In other words, it should be read top-to-bottom, left-to-right; an exact mirror of the original.

All dates have been left in their original format as opposed to converted to Gregorian calendar dates. However, all have been checked for accuracy according to the Gregorian dates we have available from other sources in the collection. Many jokbo have mistakes, and these two pages appear to have only one, that being a discrepancy in Song Yo-heon’s date of death. Thomas’ papers indicate he died in 1962; this jokbo records his death as in 1986. An investigation will be conducted to determine which is correct.

Below is the same image of pages 268-269, annotated with brackets that show what portion is in the translation spreadsheet, as well as the locations of family members and their relationship to Thomas and Albert Song:
