While John Travolta is one of Hollywood's biggest and most longstanding stars, to his five siblings, he's the baby of the family.
The Grease icon, who is now 70, has three sisters Ellen, Ann and Margaret, and brothers Samuel and Joseph – and while John is the biggest star in the family, his siblings are no strangers to the spotlight either.
Given that the Travolta matriarch, Helen Cecilia, was an actress as well as a high school drama teacher, it's no surprise her kids went on to be icons in the entertainment industry.
Read on to meet each of John's brothers and sisters – and learn the shows and films they starred in.
Ellen Travolta, 85
The oldest of the Travolta siblings, Ellen, shares her baby brother's love of acting – though on a smaller scale than his Hollywood career.
Ellen made a name for herself in sitcoms, starring in Happy Days and the show's spinoff Joanie Loves Chachi, but she also acted alongside John in Grease, making a small appearance as a waitress.
The brother-sister duo also shared the screen in 1970s sitcom, Welcome Back, Kotter.

Ellen still acts to this day, producing and performing in local theater where she lives in Idaho.
John is immensely proud of his older sister, saying of her local performances: "I don't think I've missed any of the shows there."
Ellen is mother to a son, actor Tom Fridley and a daughter, Molly Allen Ritter.

Sam Travolta, 80
John's second oldest sibling, Sam Travolta, is also an actor, though less well-known than John and Ellen, starring in films with John including Wild Hogs in 2007, Sword Fish in 2001 and Old Dogs.
John's oldest brother was struck by tragedy in 2020, when his son, Sam Travolta Junior, sadly died aged 52. John's nephew was a screenwriter who previously revealed his famous uncle gave him a $1,800 allowance to help him when times were tough.
His cause of death was not made public.

Joseph Travolta, 74
Mostly known as Joey, Joseph Travolta is closest in age to John. While he obtained a college degree in special education, Joey began a singing career in 1978, before switching to the family business of acting, starring in movies including Beverly Hills Cop III, Oscar and Susan's Plan, as well as in TV shows such as Movie Stars.
Unlike his brothers and sisters, Joey preferred directing and he combined his flair for being behind the camera with his passion for disability advocacy by founding the production company Inclusion Films in 2007, which works on projects with casts and crew members who have developmental disabilities.
