Joan “Muffet” Hemingway: Ernest Hemingway’s Eldest Granddaughter

When people think of the Hemingway name, Ernest usually comes to mind first — and then his granddaughters Margaux and Mariel, both of whom became Hollywood fixtures. But there’s a third Hemingway sister who came before them both. Joan Whittlesey Hemingway, known to family and friends as “Muffet,” is the eldest granddaughter of one of America’s greatest writers. An actress and author in her own right, Joan has carved out her own path while living under a family name that carries enormous weight — and no small amount of tragedy.

Early Life and Background

Where Was Joan Hemingway Born and Raised?

Joan Hemingway was born in 1950 and spent her earliest years in two very different worlds. She was raised partly in Havana, Cuba, where her grandfather Ernest Hemingway had made his home at Finca Vigía, and partly in Ketchum, Idaho, the small mountain town where the Hemingway family had deep roots. It was a childhood split between tropical warmth and rugged Western landscapes — an unusual upbringing, but then again, nothing about the Hemingway family was ever ordinary.

Growing up in Ketchum meant being surrounded by the outdoors. The town sits in Idaho’s Wood River Valley, and the Hemingways were well known there. Joan and her sisters spent time fishing, hiking, and living the kind of active life their grandfather had always championed. But the shadow of Ernest’s fame — and his struggles — was never far away.

Who Are Joan Hemingway’s Parents?

Joan’s father was Jack Hemingway, Ernest Hemingway’s eldest son. Jack — sometimes called “Bumby” — was a fascinating figure in his own right. He served in World War II, was captured by the Germans, and later became a well-known conservationist and outdoorsman in Idaho. Joan’s mother was Byra Whittlesey Hemingway, known as “Puck,” who married Jack in 1949. The couple had three daughters together: Joan (the eldest), Margaux, and Mariel.

Jack and Puck eventually divorced, and the three girls navigated the split along with the larger pressures that came with the Hemingway name. Jack remained a presence in their lives and was deeply involved in Idaho’s fishing and wildlife conservation efforts until his death in 2000.

Joan Hemingway’s Famous Family

How Is Joan Hemingway Related to Ernest Hemingway?

Joan is the granddaughter of Ernest Hemingway, the Nobel Prize-winning author of The Old Man and the Sea, A Farewell to Arms, and For Whom the Bell Tolls. She’s the eldest daughter of his firstborn son, Jack. That makes her the first of Ernest’s granddaughters — a distinction that put her in the unique position of being old enough to have real memories of her grandfather before his death in 1961.

Ernest Hemingway took his own life on July 2, 1961, in the family home in Ketchum. Joan was around eleven years old at the time. The loss cast a long shadow over the entire family, and it was far from the last tragedy the Hemingways would face.

Joan, Margaux, and Mariel Hemingway

The three Hemingway sisters each took a different path. Margaux, born in 1954, became a supermodel and actress — she was the first model to sign a million-dollar contract and starred in the 1976 film Lipstick. Mariel, the youngest, born in 1961, earned an Academy Award nomination at age sixteen for her role in Woody Allen’s Manhattan and has maintained a steady acting career for decades.

Joan, as the eldest, watched both of her younger sisters rise to fame. She pursued her own creative interests but did so more quietly. The sisters’ bond was tested by the pressures of public life and the mental health struggles that ran through the Hemingway family. Margaux Hemingway died on July 1, 1996, in Santa Monica, California. She was 41 years old. Her death — which came almost exactly 35 years after Ernest’s — was a devastating blow to the family.

Mariel has since become an outspoken advocate for mental health awareness, often speaking publicly about the Hemingway family’s history with depression and suicide. She directed the 2013 documentary Running from Crazy, which explored these themes head-on.

Career and Professional Life

Joan Hemingway’s Acting Career

Joan stepped in front of the camera for several film projects over the years. While she never reached the same level of mainstream recognition as Margaux or Mariel, she appeared in a handful of films and brought her own sensibility to the work. Her acting career was more selective than prolific — she seemed to choose roles that interested her rather than chasing stardom.

It’s worth noting that all three Hemingway sisters gravitated toward the arts, each in her own way. For Joan, acting was one piece of a broader creative life rather than the whole of it.

Joan Hemingway as a Writer

Given her lineage, it’s perhaps not surprising that Joan also turned to writing. She co-authored Rosebud, a thriller published in the 1970s that dealt with political intrigue and terrorism. The book was later adapted into a film. Writing allowed Joan to connect with the Hemingway literary tradition on her own terms — not as Ernest’s granddaughter trying to replicate his style, but as an author exploring her own interests and voice.

Joan’s writing career didn’t produce a massive bibliography, but it showed that the creative impulse ran strong in the Hemingway bloodline across multiple generations and across different mediums.

Where Is Joan Hemingway Now?

Joan “Muffet” Hemingway has kept a relatively low profile in recent decades. Now in her mid-seventies, she’s largely stepped away from public life. Unlike her sister Mariel, who remains active in Hollywood and as a wellness advocate, Joan has chosen a quieter existence.

That privacy is understandable. The Hemingway name has always attracted intense scrutiny, and the family’s history of loss — from Ernest’s death in 1961 to Margaux’s in 1996 — has been dissected endlessly in books, documentaries, and articles. For Joan, stepping out of the spotlight may have been less about retreating and more about finding peace on her own terms.

What’s clear is that Joan Hemingway, the eldest of the three famous Hemingway sisters, lived a life shaped by extraordinary circumstances. She grew up in the shadow of one of America’s most celebrated writers, watched her sisters become famous, endured profound family losses, and still managed to build her own creative identity as both an actress and a writer.
