Joseph Fiennes didn’t just grow up with a famous brother. He grew up in a creative laboratory where five of six siblings became artists, filmmakers, and musicians, and the sixth chose a completely different path entirely.
The Handmaid’s Tale star is one of six children born to photographer Mark Fiennes and novelist Jennifer Lash, known to everyone as Jini. The family lived a bohemian existence, moving between East Anglia, Wiltshire, London, and West Cork, Ireland, while their mother instilled a fierce creative drive in all of them.
Here’s the complete guide to Joseph Fiennes’ siblings and the remarkable family that shaped him.
Ralph Fiennes: The Oscar-Nominated Actor
Ralph Nathaniel Twisleton-Wykeham-Fiennes, born December 22, 1962, is the eldest of the six siblings and the most famous among them. He launched his film career as Heathcliff in Wuthering Heights (1992) before earning Academy Award nominations for Schindler’s List, The English Patient, and Conclave. He also gained global recognition as Lord Voldemort in the Harry Potter films.
Joseph rarely speaks publicly about Ralph, but when he does, he expresses profound respect. Ralph, for his part, told People magazine he’d love to work with his younger brother someday, calling Joseph “a brilliant actor” and joking that he’s “far too handsome.”
Martha Fiennes: The Film Director
Martha Fiennes is a director who has helmed two feature films, Onegin (1999) and Chromophobia (2005), both starring Ralph. Her most recent work is Nativity, a digital installation displayed at Covent Garden, featuring a soundtrack composed by her brother Magnus.
Martha and Magnus have spoken openly about their creative partnership, with Martha calling her younger brother a “genius.”
Magnus Fiennes: The Composer and Producer
Magnus Hubert Twisleton-Wykeham-Fiennes, born November 21, 1965, is an English composer, record producer, and songwriter. He has composed numerous film and television scores, including those for Martha’s films, and has worked with major acts like Pulp, Tom Jones, and Marianne Faithfull.
His work spans pop production and orchestral composition, making him one of the most versatile artists in the family.
Sophie Fiennes: The Documentary Filmmaker
Sophia Victoria Twisleton-Wykeham-Fiennes, born February 12, 1967, is an English film director and producer known for her arts documentaries. She trained under director Peter Greenaway and managed a dance company before turning to documentary filmmaking.
Sophie recently described the Fiennes upbringing as a kind of “creative experiment,” a sentiment her siblings share.
Jacob Fiennes: The Conservationist Twin
Jacob Fiennes is Joseph’s twin brother, born May 27, 1970. Unlike his five artistic siblings, Jacob chose a completely different path. He works as a conservationist and gamekeeper on the Raveningham Estate in Norfolk.
Joseph and Jacob were the youngest of the six siblings, born just moments apart.
Michael Emery: The Foster Brother
The Fiennes family also included a foster brother, Michael Emery, who became an archaeologist. While not a biological sibling, Michael was raised alongside the Fiennes children and is counted among the family’s seven children in some accounts.
The Matriarch Who Made It All Possible
The creative output of the Fiennes siblings didn’t happen by accident. Their mother, Jennifer Lash, was a novelist and painter who encouraged each child to pursue whatever they loved, as long as they did it to the best of their abilities.
“My mother was amazing at encouraging us,” Magnus recalled. “Her mantra was whatever you wanted to do, whether you wanted to be a dustman or a zookeeper, that was absolutely brilliant.”
Jini died of breast cancer in 1993 at just 55 years old, before she could see the full extent of her children’s success. But her influence is evident in every one of them.
The Bottom Line
Joseph Fiennes is one of six siblings, five of whom built careers in the arts and one who chose conservation. Ralph is the Oscar-nominated actor. Martha is the director. Magnus is the composer. Sophie is the documentarian. Jacob is the gamekeeper. And Joseph is the actor who followed his brother into the family business and made it entirely his own.
They grew up in a chaotic, creative household where art was the air they breathed. And they’ve spent their lives proving their mother right.
