The children’s upbringing is a blend of Irish heritage, global travel, and an introduction to the world of combat sports, often seen sparring lightly with their famous father.
The newest addition, Mack, born in late 2023, solidified the family as a unit of six, a significant milestone celebrated by fans and the media alike. The children are not just accessories to his fame; they are the central focus of his life outside the Octagon, frequently cited as his motivation for continued success and his ultimate legacy.
1. Conor Jack McGregor Jr.
The firstborn, Conor Jr., holds a special place in the family narrative. He was born at the height of McGregor's career, just months before the historic boxing match against Floyd Mayweather Jr. His early life has been documented extensively, often showing him training with his father, mirroring the famous "Notorious" walk, and learning the basics of boxing and athleticism.

Her name, Croía, is an Irish term meaning "heart," which is often used by the couple to describe her warm and affectionate personality. Her arrival diversified the family dynamic, providing a different perspective to the primarily male-dominated world of combat sports that her father and older brother inhabit. She is frequently seen in playful family photos, often dressed in complementary outfits with her mother, Dee Devlin.

Rían, the third child, was born in the spring of 2021, a time when McGregor was focusing heavily on his return to the UFC. His name, also Irish, means "little king," a fitting title for the son of a man who calls himself "The King" and "The Notorious."

Mack's arrival has brought a new level of focus on the family’s home life and their commitment to raising their children in their opulent Dublin home and various international residences.

From Octagon to Altar: The Latest Family Milestone
The most recent and significant update regarding the McGregor-Devlin family is their official marriage. After years of being engaged, Conor McGregor and Dee Devlin officially tied the knot in a discreetly exquisite ceremony on December 12, 2025, at a historic church in Vatican City, Rome. This event, which took place just before Christmas, was a deeply meaningful milestone, signifying the formalization of their 17-year partnership and their commitment to their four children.
The choice of the Vatican for their wedding venue was unexpected for the often-controversial fighter, highlighting a desire for a traditional, intimate, and exclusive celebration. The wedding marks the end of an era where Devlin was referred to as his "fiancée" and the beginning of a new chapter where she is officially his wife, the mother of his four children, and the co-head of the McGregor empire.
The Notorious's Approach to Fatherhood
Despite his aggressive public persona, McGregor's image as a father is overwhelmingly positive and hands-on. He frequently shares moments of teaching his children, particularly Conor Jr., the fundamentals of boxing and fitness, emphasizing discipline and confidence. He has shown a unique, gentle side, with videos of him holding his babies going viral, demonstrating a special "McGregor carry" technique to calm them.
The children's lives are a blend of luxury and discipline. They are often seen on McGregor’s personal yacht, "The 188," or at one of his many properties, yet the core message he promotes is one of hard work, financial literacy, and the importance of family support. By introducing them to the world of combat sports early, McGregor appears to be instilling the same fighting spirit and mental toughness that powered his rise from a Dublin plumber to a global sports icon and a successful entrepreneur with the Proper No. Twelve brand.
As Conor McGregor continues to navigate his career—with whispers of a major UFC return and ongoing business ventures—his family remains his ultimate priority. The four children are not just his legacy; they are the audience for his continued success, with the newly married couple setting a powerful example of commitment and enduring partnership.
