Seargeoh Stallone is famously known as the private second son of Hollywood action icon Sylvester Stallone and his first wife, Sasha Czack. While public fascination usually focuses on his famous father or his late brother Sage, understanding Seargeoh's background requires looking further back at the generational roots. His paternal grandparents were Frank Stallone Sr. and Jackie Stallone, figures who shaped a multi-ethnic, hard-working family lineage long before Hollywood fame entered the picture.
Tracing this lineage reveals an immigrant story rooted in resilience, working-class grit, and ambition. From southern Italy to Washington, D.C., the ancestors who came before Seargeoh built the foundation that eventually propelled the family into the public eye.
Paternal Grandfather: Frank Stallone Sr.
Seargeoh’s paternal grandfather, Francesco "Frank" Stallone Sr., was born in Gioia del Colle, Italy, in 1919. He was the son of Silvestro Stallone and Pulcheria Nicastri, ordinary working people in a small southern Italian town. Silvestro worked as a local barber, passing down a trade and a strong work ethic to his children.
In 1932, the Stallone family immigrated to the United States, seeking stability and opportunity. Life in America wasn't an immediate success story; it demanded grit. When World War II broke out, Frank Sr. answered the call, serving in the U.S. Army from 1940 to 1945.
Returning from military service, Frank Sr. built a life in New York City through sheer physical labor and entrepreneurship. He opened multiple barbershops and later built a successful career as a polo enthusiast, writer, and hairdresser. He instilled a relentless drive in his sons, Sylvester and Frank Jr., teaching them that survival required toughness.
Paternal Grandmother: Jackie Stallone
On the other side of Seargeoh’s paternal lineage was Jacqueline Frances Labofish, better known as Jackie Stallone. Born in Washington, D.C., in 1921, Jackie brought a completely different energy to the family dynamic.
Jackie’s parents were John Paul Labofish and Jeanne Victoria Anne Clerec. Her paternal grandparents, Charles and Rose Labofish, were Jewish immigrants who fled Odessa, Ukraine, during a period of intense upheaval in Eastern Europe. Her maternal side stretched back to France, giving Jackie a diverse European heritage.
Jackie was a trailblazer in her own right. Long before her sons became household names, she worked as a dancer, astrologer, and public promoter, famously involved with the Gorgeous Ladies of Wrestling (GLOW). She was eccentric, outspoken, and fiercely ambitious, characteristics that heavily influenced Sylvester Stallone’s own relentless pursuit of stardom during his struggling early days in New York.
Maternal Grandparents and Background
While less documented in mainstream celebrity profiles, Seargeoh's maternal grandparents—the parents of Sasha Czack—completed a background characterized by ordinary, hardworking American roots. Sasha Czack, born Alexandra Jane Czack, raised her family with a strong emphasis on privacy, especially after Seargeoh was diagnosed with autism at an early age.
The contrast between the loud, flamboyant public persona of paternal grandmother Jackie Stallone and the quiet, protective environment provided by Sasha and her family shaped Seargeoh's upbringing. He grew up shielded from media exposure, protected by parents who understood the pressures of public life.
How the Bloodline Shaped Sylvester and Seargeoh
The combination of Frank Stallone Sr.’s immigrant resilience and Jackie Stallone’s theatrical tenacity created a high-pressure, ambitious family culture. Frank Sr. had clawed his way out of poverty in Apulia, and Jackie refused to accept ordinary limits.
When Sylvester Stallone struggled for years as a starving actor in New York—sleeping in bus stations and writing scripts out of desperation—he was drawing on that exact generational stubbornness. That same bloodline trickled down to Seargeoh, though manifested differently. Diagnosed with autism as a toddler, Seargeoh's life journey required a quiet, internal resilience rather than the public grit of his father and grandfather. His family rallied around him, providing long-term care and a secure, private environment that respected his individual needs.
