The Five Children of the Hargitay-Mansfield Dynasty

The intricate family structure is a result of Jayne Mansfield’s three marriages and Mickey Hargitay’s three marriages. The children share various combinations of parents, but all share the common bond of their unique childhood and the trauma of losing their mother at a young age, a theme explored heavily in Mariska’s recent documentary.

1. Tina Hargitay (Half-Sister)

Tina Hargitay is Mariska's oldest half-sister, born in 1949 from Mickey Hargitay's first marriage to Mary Birge. She is the most private of all the siblings and is described as being "most unlike" her famous family. Tina has intentionally stayed out of the public eye, choosing a life away from the Hollywood scrutiny that defined her father and stepmother's careers. Her existence is a testament to the fact that not all children of famous parents choose the spotlight.

2. Jayne Marie Mansfield (Half-Sister)

Jayne Marie Mansfield was born in 1950 and is the first child and eldest daughter of Jayne Mansfield, from her first marriage to Paul Mansfield. Like her mother, Jayne Marie pursued a career in the entertainment industry as an actress and model. She has often spoken about her mother's legacy and has a passion for the arts that remains unwavering. Notably, she was the only one of Jayne Mansfield's five children to attend her funeral in 1967. She is currently exploring new creative ventures within the industry.

3. Miklós "Mickey" Hargitay Jr. (Full Brother)

Mickey Hargitay Jr. was born on December 21, 1958, and is Mariska's full older brother, the first child of Jayne Mansfield and Mickey Hargitay. While he has roots in the film industry, he has carved out a unique and unexpected career path far removed from acting. Mickey Jr. currently owns and operates a successful plant shop in central Hollywood, embracing a connection to nature and the earth rather than the silver screen. His business has become a local fixture, and he has spoken about his Hollywood roots in connection with his plant shop.

4. Zoltán Hargitay (Full Brother)

Zoltán Hargitay was born on August 1, 1960, and is the second son of Jayne Mansfield and Mickey Hargitay, making him Mariska's other full older brother. Like his brother Mickey Jr., Zoltan works in the entertainment industry but prefers to remain behind the scenes. He has established a successful, quiet career as a carpenter on Hollywood sets. This work allows him to stay connected to the world of film while maintaining a private life shaped by resilience and strength following the family's early tragedy.

5. Antonio "Tony" Cimber (Half-Brother)

Antonio "Tony" Cimber was born in 1965 and is the youngest of all the siblings. He is the son of Jayne Mansfield and her third husband, director Matt Cimber. Tony has recently become a focal point of the family's public narrative due to his involvement in Mariska's documentary, *My Mom Jayne*. In the film, Mariska and Tony delve deep into their shared family trauma and their mother’s legacy. Tony's willingness to share his memories and confront the past alongside his sister provides a fresh and moving perspective on the challenges faced by the family.

The Documentary That Revealed a Family's Shared Trauma

The most important and current piece of information regarding the Hargitay siblings’ relationship is the 2025 release of *My Mom Jayne*. This documentary, which Mariska Hargitay directed, is not just a tribute to Jayne Mansfield; it is a profound act of healing and shared remembrance for the family.

The film focuses heavily on the lasting impact of their mother’s death and the subsequent trauma on her children. Mariska, who was only three years old when her mother died, uses the film as a way to understand the woman she barely knew and to confront the past with her siblings.

Tony Cimber, in particular, shares intimate details and personal reflections that help Mariska and the audience piece together their mother's complex life. The documentary shows a powerful, supportive connection between Mariska and Tony, emphasizing that despite their different fathers, the siblings share an unbreakable bond forged by their shared mother and the need to process their difficult history together.

The documentary also touches on the unique experience of being raised by their father, Mickey Hargitay, after Jayne Mansfield’s death. Mickey's dedication to raising his children, including his stepdaughter Jayne Marie and his own three children with Jayne, is a key part of the Hargitay family's narrative of resilience.

In a world where celebrity families often fall prey to public feuds, the Hargitay siblings—Tina, Jayne Marie, Mickey Jr., Zoltan, Mariska, and Tony—demonstrate a powerful, albeit private, unity. Their individual lives, from running a plant shop to working as a Hollywood carpenter, are grounded and successful. The recent documentary *My Mom Jayne* serves as a powerful reminder that their shared legacy is not just one of Hollywood glamour and tragedy, but one of deep, enduring familial love and the courage to confront family trauma together.
