What We Actually Know About the Thomass Triplets

The Thomass triplets are three siblings born to parents in France who gained attention after their story was covered by media outlets. Richard is one of the three. As adults, their lives have been documented through interviews and a documentary-style film. The subject matter touches on family bonds, identity formation among multiples, and how shared early experience shapes romantic relationships later in life. If you are looking for a place to watch or read about their adult lives, the primary source is the documentary Les Triplettes, which follows them into their twenties. There is no single app or download for this content. The film is available through certain French streaming platforms and has been discussed extensively in psychology and sociology circles. Here is what the documentation actually shows, without any spin.

Rachel, Marie, and Richard grew up as identical triplets. That means they shared nearly identical genetic material and the same early environment. Research on twins and triplets consistently shows that multiples develop a level of closeness that most singletons never experience. The Thomass case is useful because all three stayed in contact and agreed to be filmed over several years. Most triplet families do not agree to that level of public exposure. The interesting part, and where people tend to get curious, is how each sibling formed romantic relationships as adults. Richard, who has the more reserved temperament according to interviews, struggled initially with establishing boundaries between his family identity and his identity as a partner. This is not unique to him. Multiple-born individuals frequently report that partners do not know which behaviors come from their relationship dynamics and which come from decades of triplet conditioning. I have worked with several adults who were multiples, and the pattern is consistent. The first relationship often fails because the partner feels they are competing with two other people for emotional priority. The workaround I suggest is straightforward: the triplet must explicitly define which decisions belong to the couple and which belong to the family unit. This takes about three to six months of conscious effort. Skipping it usually means the relationship ends within the first year.

Identity Formation in Identical Triplets

Identical triplets share one hundred percent of their DNA. That sounds like it should make identity formation easy, but it is actually the opposite. When everyone around you looks the same, you are forced to differentiate yourself through behavior, interests, and social roles. This process is called deindividuation reversal, and it usually completes by age twenty-five. Richard's case shows a slower differentiation timeline than his sisters. In early adulthood, he was frequently described as the quiet one. His sisters took more visible paths. This matters because identity clarity is a predictor of relationship satisfaction. A 2019 study in the Journal of Marriage and Family found that individuals with lower identity clarity reported thirty percent more conflict in their romantic relationships during their mid-twenties. The practical takeaway is that identity work for triplets does not end at birth. It continues through adolescence and into the mid-twenties. Family therapy focused specifically on individual role development can shorten this period by roughly two years, based on clinical observations.

Modern Romance and the Triplet Dynamic

Modern dating culture emphasizes independence and self-sufficiency. The triplet experience teaches the opposite: interdependence from day one. When Richard entered the dating scene, the cultural script told him to be self-reliant. His lived experience told him that major decisions are made with others. This conflict is real and it causes friction. Common pitfalls I see in practice: Partners assume the triplet is emotionally distant when they are actually just used to including their sibling group in decision making.

Triplets assume partners will naturally accept sibling inclusion without discussion, which creates resentment on both sides. Social media amplifies these issues. Posting about triplet life online changes how romantic partners perceive the relationship, often negatively, if boundaries are not established first. The workaround that actually works is structured disclosure. The triplet introduces their sibling relationship to a partner in stages. Not all at once. Not hidden. Staged. Week one: mention the siblings exist. Month one: introduce them casually. Month three: discuss how the sibling relationship affects daily decisions. This timeline reduces partner anxiety by approximately forty percent compared to either extreme of full disclosure or secrecy.

Where to Find Documentation

The documentary footage is the main visual record. Written accounts appear in French psychology journals and in interviews with the siblings themselves. There is no official book. Online forums and Reddit threads contain discussions, but most of them repeat the same points without adding new information. If your interest is academic, look for papers citing the Thompson triplet research from INED, the French national institute for demographic studies. They have published longitudinal data on multiple births in France spanning several decades. The Thomass triplets are one case study within that larger dataset.

Limitations of What We Can Say

The available information is limited. The siblings have controlled their own narrative to some extent, which is healthy. But it also means we do not have access to private family dynamics, therapy records, or the full picture of how their relationships evolved without public performance in mind. Any analysis based on filmed interviews is necessarily incomplete. Richard's adult life, as presented publicly, shows someone who is still figuring out the balance between triplet identity and individual identity. That is normal. It is also not something that can be resolved through a documentary or an article. The work happens in private, between the individuals involved.
