Kinship, Polygamy, and Small Communities: Understanding the Revelation from Sister Wives

Reality television often blurs the line between entertainment and social documentation, offering audiences a window into family structures that differ from mainstream norms. This dynamic was recently highlighted when Sister Wives star Christine Brown revealed that she is distantly related to her former husband, Kody Brown. While the revelation surprised viewers—and even Christine’s current husband—it also sheds light on broader sociological patterns common in small, close-knit religious communities.

Christine explained that she and Kody are “third cousins once removed,” a relationship that is legally permissible and genetically distant. Although such a connection may seem unusual or shocking to outsiders, sociologists and anthropologists note that distant kinship ties are relatively common in insular populations where marriage networks are limited. Research on endogamous and semi-endogamous communities shows that repeated intermarriage across generations naturally increases the likelihood of distant familial overlap (bold: Ember & Ember, 2007, Cultural Anthropology).

The Sister Wives family emerged from a fundamentalist Mormon background, where plural marriage historically developed within small religious networks. In such environments, social circles, religious affiliation, and family ties frequently intersect. Anthropological studies of polygamous communities in North America suggest that distant cousin relationships are not only common but often normalized, particularly when the community emphasizes shared belief systems over genetic distance (bold: Bennion, 2012, Polygamy in Primetime).

Christine’s comments also reflect an awareness of these dynamics from an early age. She noted that she expected to marry a convert because she was “related to everybody in the church.” This statement aligns with sociological findings that individuals raised in closed communities often recognize kinship saturation as a practical reality rather than a taboo (bold: Heaton, 2001, Journal for the Scientific Study of Religion). The fact that Christine still ended up related to Kody underscores how limited marriage pools can override personal expectations.

The revelation prompted discussion among viewers not only about kinship, but also about legality and social norms. Christine’s emphasis that their relationship was “fully legal” highlights how modern audiences often conflate legality, morality, and cultural comfort. Scholars note that discomfort with cousin relationships in Western societies is largely cultural rather than biological, especially when genetic distance is significant (bold: Bittles, 2001, Annual Review of Anthropology).

Adding further complexity to the family structure, fellow Sister Wives cast member Janelle Brown revealed that her mother married Kody’s father shortly before Janelle herself married Kody. Family scholars describe such overlapping marital ties as “affinal convergence,” a phenomenon that occurs when marriage reinforces existing social bonds within a small group (bold: Stone, 2010, Kinship and Family). While this may appear unconventional, it reflects how family systems adapt to maintain cohesion and continuity.

Media response to Christine’s revelation illustrates how reality television magnifies culturally specific practices into moments of spectacle. According to media studies research, reality TV often frames non-normative family arrangements as “shocking,” reinforcing mainstream assumptions while simultaneously normalizing them through repeated exposure (bold: Couldry, 2012, Media, Society, World). In this sense, Sister Wives functions both as entertainment and as a case study in alternative family organization.

In conclusion, Christine Brown’s confirmation that she and Kody Brown are distant cousins is less a scandal than a reflection of sociological realities within small, insular communities. When viewed through the lenses of anthropology and family studies, such relationships are understandable outcomes of limited marriage networks rather than anomalies. The public reaction reveals more about societal expectations and cultural distance than about the family itself, reminding viewers that concepts of “normal” family life are deeply shaped by context, history, and community size.
