In 'The Foursome,' conjoined twins marry two sisters — and that’s just the beginning

By NPR (podcasts@npr.org)

In this episode of NPR's Book of the Day, Ayesha Rascoe interviews novelist Christina Baker Kline about her fictionalization of Chang and Eng Bunker, the conjoined twins from Siam who settled in 19th-century North Carolina. The conversation explores the twins' remarkable journey from exploitation as circus exhibits to becoming wealthy property owners who married two sisters and shared a single household.

Kline discusses the central contradictions in the Bunkers' story, particularly how the twins transitioned from being commodified themselves to becoming slaveholders in the antebellum South. The interview examines the complex dynamics of the four-person marriage, the community's reaction to their unconventional arrangement, and Kline's approach to portraying historical figures as multifaceted individuals rather than curiosities. Through characters like Grace Gates, an enslaved woman central to the household, the novel grapples with themes of power, complicity, and the moral complexities of seeking acceptance within unjust systems.

Chang and Eng Bunker: Historical Reality and Fictional Adaptation

Novelist Christina Baker Kline discusses her fictionalization of Chang and Eng Bunker's extraordinary lives with Ayesha Rascoe. Born in 1811 in Siam as conjoined twins, Chang and Eng were initially exploited by a British merchant who displayed them around the world. The twins eventually reclaimed control of their careers and accumulated enough wealth to retire by age 29, settling in northwestern North Carolina.

Kline's novel was inspired by a mysterious detail: Eng's wife Sarah chose to be buried separately from the family plot, in an unmarked grave on her own property alongside deceased daughters and formerly enslaved people. This decision, unexplained by historical records, became a focal point for Kline's fictional exploration of the Bunker family dynamics. While descendants of the twins provided feedback on an early manuscript, they understand the work is Kline's interpretation, not strict historical fact.

Motivations and Dynamics of a 19th-Century Cross-Racial Marriage in North Carolina

Adelaide felt an immediate attraction to Chang, but legal constraints required Eng to marry as well to avoid bigamy charges. Sarah, Adelaide's sister, was coerced into marrying Eng but eventually found ways to accept and navigate the arrangement. The household of four shared one bed, defying every social norm and sparking scandal in their North Carolina community. Despite gossip about depravity and sin, the curiosity eventually faded, though the Bunkers never achieved full acceptance, remaining on society's fringes.

Kline uses Sarah's skeptical perspective to guide readers through the family's unconventional circumstances. Through Sarah's rational engagement with her situation, the novel shows how extraordinary lives become normalized through incremental, understandable decisions, challenging assumptions and inviting empathy.

Chang and Eng's Moral Complexity In Adopting Slavery

Kline and Rascoe explore the central contradiction in Chang and Eng's story: despite their own commodification and exploitation, the twins became slaveholders in North Carolina.

From Exploited To Exploiters

Chang and Eng were sold by their mother to a British merchant and exhibited for profit, often kept in steerage. Yet when they settled in North Carolina, they adopted the very system that had denied them dignity. Kline finds it shocking that the brothers didn't recognize the irony of this transition from being treated as property to treating others as such, suggesting a disconnect between their trauma and moral reflection.

Gaining Respectability Through Power Structures

Although North Carolina law was meant to restrict Asian men, a legal loophole allowed Chang and Eng to circumvent these policies. Kline observes that the twins saw assimilation into the local elite required adopting its customs, including slaveholding. By subjugating others, as Rascoe notes, they gained a foothold in Southern society, transforming their own marginalization into social and economic power.

Grace Gates and the Household's Moral Landscape

A key figure in exploring this complexity is Grace Gates, an enslaved woman raised alongside Sarah and Adelaide who was given to the twins as a wedding gift. Grace's lifelong relationship with Sarah, marked by both intimacy and complicity, offers insight into the emotional bonds that existed within the constraints of power and moral contradiction.

Portraying Historical Figures As Complex Individuals

Kline's portrayal focuses on presenting Chang and Eng as real people shaped by their time and circumstances, not distant curiosities.

Success and Complicity

Kline emphasizes that the twins epitomized the immigrant success story, arriving with nothing and creating remarkable wealth through intelligence and strategy. However, she doesn't shy away from their flaws, describing them as fallible men whose choices reflected both resilience and complicity in unjust systems.

Distinct Personalities

Kline carefully distinguishes Chang from Eng, making their individual personalities clear as the story unfolds. This nuanced approach extends to Sarah and Adelaide, whose different temperaments and desires shaped the household dynamics. By immersing readers in the everyday lives of her subjects, Kline encourages them to see these historical figures as full human beings with agency and humanity rather than as curiosities. As one character notes in the novel, "even the most extraordinary life feels ordinary when you're living it."

Counterarguments

  • While Kline's novel is inspired by historical events, some may argue that fictionalizing real people—especially those from marginalized backgrounds—risks misrepresenting their experiences or motivations, even with descendant input.
  • The focus on Sarah's burial decision as a narrative catalyst may overemphasize a single unexplained event, potentially overshadowing other significant aspects of the Bunker family's history.
  • The portrayal of Chang and Eng's adoption of slavery as primarily a means to gain respectability could be critiqued for not fully addressing the broader context of economic motivations or the pervasive normalization of slavery in the antebellum South.
  • Emphasizing the normalization of extraordinary lives through "incremental, understandable decisions" might risk downplaying the real social and psychological costs of such arrangements for all involved, especially the enslaved individuals.
  • The narrative centers the perspectives and agency of the Bunker family, which could inadvertently marginalize the voices and experiences of enslaved people like Grace Gates, whose stories are equally vital to understanding the household's dynamics.
  • Presenting Chang and Eng as "immigrant success stories" may gloss over the ethical implications of their participation in slavery and the suffering of those they enslaved.

Actionables

  • you can reflect on your own family or community traditions that once seemed unusual but became normal over time, then write a short journal entry about how those incremental changes shaped your current values or routines; for example, consider how your family’s approach to holidays, relationships, or work evolved and what small decisions led to those shifts.
  • a practical way to challenge assumptions about people’s choices is to pick a historical figure or ancestor whose actions you find troubling, then list possible social pressures or circumstances they faced, and brainstorm how you might have acted in their place; this helps build empathy and a nuanced understanding of complex decisions.
  • you can examine your own participation in systems or customs that might conflict with your values by making a two-column list: on one side, write down practices you benefit from or participate in (like fast fashion, certain workplace norms, or social media habits), and on the other, note any ethical concerns or discomforts you have about them; use this list to identify one small change you could make to better align your actions with your values.

Chang and Eng Bunker: Historical Reality and Fictional Adaptation

Chang and Eng's Resilience and Business Acumen Before Settling In Nc

Chang and Eng Bunker were born in 1811 in a small fishing village in what was then Siam, Thailand. They were conjoined twins, joined by a simple band of cartilage below their ribs on one side, but each had two arms, two legs, and a head. Despite their condition, they lived active lives—fishing, building houses, hunting, and taking on acrobatics such as backflips and somersaults to earn a living.

Their lives changed dramatically when a British merchant spotted them and persuaded their mother and the king to allow the twins to travel with him, offering their mother more money than she had ever seen. The merchant’s intention was to display them around the world. However, the twins realized that they were being exploited by this manager, who traveled first class while relegating them to steerage accommodations. Eventually, Chang and Eng managed to reclaim control over their careers and, through performing, amassed enough wealth to retire by the age of 29. They settled in northwestern North Carolina, achieving financial independence at a young age.

Novelist Uses History to Imagine Family Dynamics Beyond Official Records

In Mount Airy, North Carolina, the cemetery holding the headstone for Chang, Eng, and their wives (who were sisters) contains the remains of only three family members. Eng’s wife, Sarah, chose instead to be buried on her own property in an unmarked grave alongside their four daughters who predeceased her and formerly enslaved people who, after the Civil War, had returned to the farm. The reason for this decision remains unknown.

This mysterious separation inspired novelist Christina Baker Kline to ...

Motivations and Dynamics of a 19th-Century Cross-Racial Marriage in North Carolina

Escape From Constrained Circumstances: Adelaide and Sarah's Attraction to the Twins

Adelaide, renowned for her beauty, charm, and sophistication, felt an immediate spark with Chang, one of the conjoined twins. However, social and legal constraints made their union complex. It was considered bigamy if Ang, Chang’s brother, remained unmarried, so Adelaide’s sister Sarah was coerced—primarily by her sister—into marrying Ang despite her reluctance. Sarah entered the marriage skeptically, but over time, she came to see advantages in their unconventional household. Eventually, she found ways to navigate and accept her place within it.

Household of Four Defied Norms, Caused Scandal, but Won Acceptance Despite Marginalization

Living as a household of four who shared one bed, Adelaide, Sarah, Chang, and Ang defied every expectation and social norm in their North Carolina community. Their unusual arrangement sparked scandal; neighbors speculated and gossiped about depravity, incest, and sin, accusing them of madness and perversion. No respectable family, it was said, would allow such an abomination. Despite the initial fervor, community curiosity eventually faded. The neighbors stopped asking intrusive questions and gossip waned, but the Bunkers never achieved full acceptance. They remained on the boundary of respectability—neither embraced nor shunned, but always marked by difference and existing on society’s fringes.

Chang and Eng's Moral Complexity In Adopting Slavery

Christina Baker Kline and Ayesha Rascoe explore the striking contradiction at the heart of Chang and Eng's legacy: their own experience of commodification and exploitation, and their later decision to become slaveholders in North Carolina. This moral complexity sits at the center of their story.

Chang and Eng's History as Slaveholders Contradicts Their Own Commodification

Twins Sold by Their Mother To a British Merchant; Exploited For Profit, Kept In Steerage, Later Adopted the Same System That Denied Them Dignity

Chang and Eng’s life began with exploitation; their mother was paid a sum for them to be taken away by a British merchant. The twins were then exhibited across the world for profit, often kept in steerage. Despite this, when they settled in North Carolina, they adopted the very system that had denied them basic dignity—becoming slaveholders themselves. Christina Baker Kline finds it shocking that the brothers did not seem to recognize the irony of this transition from being treated as property to treating others as such.

From Exploited To Exploiters: Brothers' Disconnect Between Trauma and Moral Reflection

The path from exploited to exploiter raises questions about the brothers’ ability to reflect on their trauma and its moral implications. Their willingness to engage in slaveholding suggests a disconnect between their own history and their capacity for empathy or moral reflection regarding the subjectivity and suffering of others.

Twins Achieve Respectability in North Carolina By Adopting Local Power Structures Built On Racial Subjugation

Chang and Eng’s pursuit of respectability in a racially stratified society was shaped by their willingness to join, rather than challenge, the existing power structures.

Although North Carolina law was meant to prohibit citizens and marriages for Asian men, the policy applied only to free Black men, which created a loophole that allowed Chang and Eng to circumvent these restrictions. Even so, the twins faced significant anti-Asian sentiment during their touring years. Their eventual acceptance into local society was therefore precarious and dependent on fitting into the established racial order.

Brothers Gained Influence By Embracing Slaveholding and Transforming Marginalization Into Power

Kline observes that when Chang and Eng moved to North Carolina, they saw assimilation into the local elite required adopting its customs—including slaveholding. By subjugating others, as Rascoe comments, the twins gained a position and foothold in Southe ...

Counterarguments

  • While Chang and Eng’s participation in slavery is morally troubling, it is important to recognize that their actions were shaped by the prevailing norms and legal structures of 19th-century North Carolina, which may have limited their perceived options for social and economic advancement.
  • The assumption that Chang and Eng lacked empathy or moral reflection may be difficult to substantiate, as historical records often do not capture the full complexity of individuals’ private thoughts or internal conflicts.
  • The narrative of Chang and Eng “not recognizing the irony” of their transition from exploited to exploiter may oversimplify the psychological coping mechanisms and survival strategies employed by marginalized individuals navigating oppressive systems.

Portraying Historical Figures As Complex Individuals

Christina Baker Kline’s portrayal of Chang and Eng, along with their wives Sarah and Adelaide, focuses on the complexity and humanity of historical figures. Through her narrative, she presents them not as distant curiosities but as real people shaped by their time, circumstances, and distinctive personalities.

Chang and Eng Epitomized Successful Immigrant Wealth and Influence Through Ingenuity

Twins Embodied Success By Arriving With Nothing and Creating Opportunity Through Intelligence, Strategy, and Economic Awareness

Kline emphasizes that Chang and Eng were extraordinary in their accomplishments. Arriving in America as immigrants with absolutely nothing, they became the prototypical American success story. Their rise was rooted in intelligence and savvy—making their own opportunities by leveraging strategic thinking and economic awareness. Their story encapsulates the ability to transcend initial disadvantage and build remarkable wealth and influence.

Despite Their Achievements and Resilience, Chang and Eng Were Fallible Men Shaped by Society, and Their Choices Reflected Intelligence and Complicity in Unjust Systems

Kline does not shy away from their flaws or the complexities of their lives. She describes both men as complicated and fallible, shaped by the society in which they lived. Their choices, while marked by intelligence and resilience, were also influenced by—and sometimes complicit in—the unjust systems of their era, making them subjects of both admiration and critique.

Distinct Personalities For Twins and Sisters: Conjoined or Married Pairs Not Treated As Interchangeable Units

Distinct Personalities of Chang and Eng Emerge

Kline is careful to distinguish Chang and Eng from one another. As the story unfolds, readers become very clear on each man’s distinct identity and personality. By about a third of the way through the book, the differences between the twins are fully apparent, breaking the stereotype of treating conjoined twins as merely a unit.

Adelaide and Sarah's Differing Temperaments, Desires, and Marital Responses Shaped the Household Dynamics

This nuanced approach extends to Sarah and Adelaide, the sisters who married Chang and Eng. Kline highlights that they were extremely different from one another, with unique temperaments and desires. Their personal responses to their unusual marital situation shaped the dynamics of the household, contributing to the richly textured social environment that surround ...
