Cynthia Nixon has spent decades in the spotlight, but at home she is simply Mom to three kids who have grown up alongside her career and activism. Her children, Seph, Charles and Max, span different generations of her life, from her early relationship with photographer Danny Mozes to her later partnership with education advocate Christine Marinoni. Together they form a tight, politically aware family that reflects Nixon’s values just as clearly as any role she has played on screen.
Each child has carved out a distinct path, whether it is Seph’s public coming out as transgender, Charles’ quieter life away from cameras, or Max’s childhood spent watching his mother reinvent a beloved TV character. Here is how the family fits together, and what is known about the three kids who matter most in Cynthia Nixon’s world.
Cynthia Nixon’s family story and parenting style
Before diving into each child, it helps to understand the family map. Cynthia Nixon shares her two older children, Seph and Charles, with her ex boyfriend, photographer Danny Mozes, a relationship that is documented in her family biography. Later, she built a new chapter with education activist Christine Marinoni, and together they welcomed a third child, Max, expanding the household into a blended, queer family that Nixon has spoken about with pride. That mix of histories means her kids grew up with different co parenting arrangements but a shared sense that their home life was rooted in openness and political engagement.
Nixon’s approach to parenting has always sounded both grounded and unapologetically progressive. She has linked being a mom to her willingness to speak out on issues like LGBTQ+ rights and a permanent Israeli ceasefire in Gaza, describing how raising Seph, Charles and Max sharpened her sense of responsibility to the wider world and pushed her to be more vocal in public life. In one profile, she connected her activism directly to the experience of watching her children grow, noting that being a parent has helped her find her voice and stay focused on what truly matters for their future, including her support for a permanent ceasefire.
Seph Mozes, the eldest and trailblazer
The oldest of Nixon’s three children is Seph Mozes, who has become a quiet trailblazer in the family. Born Samuel Joseph Mozes and often called Samuel or Seph in earlier years, he is now known publicly as Seph Mozes, a name that reflects his own journey. Nixon and Mozes welcomed Samuel “Seph” Joseph together during their long term relationship, and she has described watching him grow up as one of the central experiences of her adult life. As the first child, Seph set the tone for the household, and his path would later shape how Nixon talked about gender, identity and parenting in public.
Seph came out as transgender as a young adult, and Nixon chose to share that milestone in a heartfelt social media post that doubled as a political statement. In that message, she celebrated her son’s courage while also marking Trans Day of Action, framing his transition as both a deeply personal family moment and part of a broader fight for trans rights. She wrote about her “firstborn child, Samuel Joseph Mozes, or Seph,” and expressed how proud she was to see him living as the man he is, language that has since been widely cited as an example of affirming parenting. The post, which appeared alongside a photo of Seph in a cap and gown, was shared on her Instagram and quickly became a touchstone for fans who saw their own families in her words.
Charles Ezekial Mozes, the middle child with a low profile
In the middle is Charles Ezekial Mozes, who tends to keep a lower profile than his siblings. Charles is also a child of Nixon’s relationship with Danny Mozes, and like Seph he grew up splitting time between his parents while watching his mother balance stage work, film roles and the cultural juggernaut of Sex and the City. Reports have noted that Charles Ezekial Mozes, 23, is Nixon’s second child, a detail that helps place him squarely between his older brother and younger half brother in age and family dynamics. While he has not been as publicly visible as Seph or Max, his presence is woven into Nixon’s occasional comments about juggling teenagers and a younger child at the same time.
Nixon has hinted that parenting Charles has been its own education, especially as he moved through adolescence while she was stepping into more overt political roles. She has spoken about watching each child “grow into her own, too,” a slightly tangled phrase that still captures how she sees her kids as independent people rather than extensions of her career. That perspective shows up in coverage that notes how Charles has been allowed to grow up largely off camera, even as his mother’s work and activism intensified. References to Charles Ezekial Mozes, 23, and the way Nixon talks about letting each child “grow into her own, too” appear in detailed profiles of her family life, including one that situates Charles between Seph Mozes, 29, and her youngest, Max Nixon Marinoni, born to Nixon Marinoni.
Max Ellington Nixon Marinoni, the youngest and scene stealer
The baby of the family, at least in relative terms, is Max Ellington Nixon Marinoni, and his arrival marked a new chapter for Cynthia Nixon and Christine Marinoni. The couple welcomed a Son together in NEW YORK, a moment that was widely covered at the time as a milestone for a high profile same sex couple. Reports noted that “Christine Marinoni and Cynthia Nixon Welcome a Son” and that both Christine and the baby were doing fine, while also pointing out that Nixon’s earlier relationship with Danny Mozes had ended in 2003. That context underscored how Max’s birth symbolized not just a new child but a fully realized second act in Nixon’s personal life, rooted in her partnership with Marinoni and their shared work in education and politics, as confirmed in coverage from CBS.
As the youngest, Max has popped up in some of Nixon’s sweetest public family moments. One widely shared snapshot showed Cynthia Nixon and her youngest child, son Max Ellington Nixon Marinoni, walking together, a reminder that even as she returns to the role of Miranda Hobbes, she is also navigating school runs and everyday parenting. Another moment that drew attention came when the 55-year-old actor posted a rare picture of Max on social media, standing alongside Niall Cunningham, the actor who plays Brady, Miranda’s son, in the Sex and the City revival. That image, shared on a Friday on her Instagram, playfully blurred the line between Nixon’s fictional and real life kids and gave fans a rare glimpse of Max as a growing boy rather than the baby many remembered from early announcements.
How motherhood shapes Cynthia Nixon’s activism and career
Across all three kids, one throughline is how openly Nixon credits motherhood with sharpening her politics and her sense of purpose. She has said that being a mom has helped her find her voice, a sentiment that shows up repeatedly when she talks about why she leans into activism instead of staying in a purely entertainment lane. In one detailed profile, she is described as the proud parent of three children, Seph, Charles and Max, and the piece links that identity directly to her willingness to speak out on issues like LGBTQ+ rights, public education and foreign policy. The same reporting notes that she has tied her advocacy for a permanent Israeli ceasefire in Gaza to the values she wants to model for her kids, underscoring how family and politics are intertwined for her, as reflected in coverage that highlights “Being a mom has helped” her activism around Gaza.
