Milo Ventimiglia and his wife, Jarah Mariano, have officially expanded their family. The “This Is Us” actor and the model welcomed their second child together, a baby boy named Rock-Anthony Makoa Ventimiglia, making them a family of five that also includes their 18-month-old daughter, Ke'ala Coral, and their dog, Duke.
Mariano announced the happy news on Instagram, sharing intimate black-and-white family photos featuring Ventimiglia, their two children, and their four-legged companion. "These last couple of weeks have been chaos, but in the best possible way," Mariano wrote alongside the photos. "Welcome back home, Rock-Anthony Makoa Ventimiglia. Can't wait for all of the adventures ahead with our family of 5!”
The sweet announcement marked another milestone for the famously private couple, who quietly married in 2023 and have largely kept their family life out of the spotlight.
Milo Ventimiglia Was Excited to Give His Daughter a Sibling
Before their son's arrival, Ventimiglia shared his excitement about becoming a father of two, especially watching his daughter step into her new role as a big sister. "I'm most excited for my daughter to have a sibling, someone to grow up with," the actor previously told People.

Their Children's Hawaiian Names Honor Jarah Mariano's Roots
Both of the couple's children have names inspired by Hawaiian culture, a meaningful tribute to Mariano's heritage. Mariano was born on the Hawaiian island of Kauai before later moving to California.
Their daughter, Ke'ala Coral, carries a Hawaiian name that means "the pathway" or "the fragrance," while their newborn son's middle name, Makoa, means "fearless." The names reflect the family's connection to Mariano's Native Hawaiian roots and continue a meaningful tradition within their growing family, as reported by Parents Magazine.

At 42, Mariano is also part of a significant demographic shift in the United States.
According to a 2025 report from the National Center for Health Statistics, births among women aged 40 and older have continued climbing, reaching a historic milestone. For the first time, people giving birth at age 40 and older outnumbered teen births.

Experts attribute the trend to several factors, including advances in fertility treatments, improved prenatal care, greater financial stability, and more women choosing to establish their careers or wait until they find the right partner before starting a family.
Mariano welcomed Ke'ala at 41 and has now given birth to her second child at 42, reflecting a path that is becoming increasingly common for women today.
A Joyful New Chapter
The arrival of baby Rock-Anthony marks a joyful new chapter for Ventimiglia and Mariano, who have experienced both heartbreak and happiness in recent years. The couple welcomed their first daughter shortly after losing their Malibu home in the California wildfires, making the growth of their family especially meaningful.
Now, with Ke'ala embracing life as a big sister, baby Rock-Anthony settling in at home, and Duke completing the family portrait, the Ventimiglia household has even more reasons to celebrate.
