Many people know Jimmy Stewart through It’s a Wonderful Life, Rear Window, and Harvey. Fewer know about the family he returned to after work. Judy Stewart Merrill is one of his twin daughters, and her story offers a closer look at that part of his life. She grew up in Beverly Hills, later married and raised children, and has helped remember her father through public events. Her family history also includes a sister who studied gorillas, brothers with different life paths, and a connection to charitable work.

Who Is Judy Stewart Merrill?
Judy is the daughter of James Stewart and his wife, Gloria. Her father was already a well-known actor when she was born. He had won an Academy Award and appeared in films that would remain popular for many years. Her connection to this film history explains why readers continue to search for her name, even though she has maintained a much smaller public profile.
Judy occasionally joined her father at entertainment events. Photographs show her and Kelly arriving with him at the Academy Awards on April 10, 1967. The twins were 15 at the time and wore matching outfits. This is one clear example of her early connection to Hollywood’s public life. Later appearances would include family tributes and events celebrating the work of the actor she knew as her father.
Her Birth and Early Life in Beverly Hills
Judy Stewart Merrill was born on May 7, 1951, on the same day as her sister, Kelly. Their parents had married in August 1949. A few months after the twins arrived, the family moved into a Tudor-style house in Beverly Hills. James and Gloria continued living there for the rest of their lives. This home was the setting for much of the twins’ childhood.
Travel was another part of the family’s life. An account of Kelly’s early interest in gorillas describes a trip to the Congo with her mother and Judy. The visit took place in 1972, when the twins were young adults. They saw gorillas at Kahuzi-Biega National Park. For readers interested in Judy’s background, this is a specific example of an experience she shared with her sister and mother beyond their California home.
Her Parents, Jimmy Stewart and Gloria Stewart
Her father’s full name was James Maitland Stewart. Audiences knew him for his gentle voice, humour, and ability to play both ordinary men and troubled characters. He was also a military veteran who served during World War II and later became a brigadier general in the Air Force Reserve. Acting and military service were both major parts of his life, alongside marriage and fatherhood.
Gloria Hatrick McLean had worked as a model and actress before marrying James. She already had two sons from her earlier marriage. She later supported community organisations, including groups connected with wildlife, museums, and health care. Understanding Gloria’s background gives a fuller picture of Judy’s family. Both parents had interests beyond the film industry, and their shared life included their children, travel, animals, and public service.
Her Twin Sister and Two Half-Brothers
Judy Stewart Merrill has a twin sister, Kelly Stewart Harcourt, who developed a career in anthropology and wildlife research. Kelly studied at Stanford University and later earned a doctorate in zoology at Cambridge. Her work included studying mountain gorillas in Africa. She and her husband, Alexander Harcourt, have written about gorilla behaviour and conservation. Those academic achievements belong to Kelly and should not be confused with Judy’s background.
The twins also had two older maternal half-brothers, Ronald and Michael McLean. They were Gloria’s sons from her first marriage, and James adopted them after marrying her. This means the Stewart household included four children. Ronald later served in the Marine Corps, while Michael followed a different path outside his father’s acting career. The family relationships can seem confusing when brief profiles describe everyone simply as siblings, but they shared the same mother.
Her Education and Her Father’s Simple Advice
A family memory offers a small but useful detail about Judy’s education. In a 2008 interview, Kelly recalled that their father spoke to both sisters as they prepared to leave for college. The twins expected a serious conversation. Instead, he gave them a short piece of advice: “Always remember, be nice to people.” Kelly said that the message stayed with her.
This story places Judy Stewart Merrill at an important stage of young adult life, but it does not establish which college she attended or what she studied. Kelly’s university record is much more widely documented. It would be easy to copy those details into Judy’s biography by mistake. What the memory clearly shows is the advice their father wanted both daughters to carry with them as they became more independent.
Her Marriage to Stephen Merrill
Family profiles date Judy’s marriage to 1979. Her husband’s first name appears as Stephen in older newspaper coverage and Steven in later profiles. By November 1985, the couple appeared together as husband and wife in society coverage. The different spellings are worth recognising because readers may encounter both while looking for information about the family.
After marriage, Judy Stewart Merrill became known publicly as Judy Merrill as well as by versions that included Stewart. These variations help explain why older photographs, family profiles, and event announcements may use different names for her. They also connect records from her childhood with those from her adult life. The available coverage establishes the marriage, but details about the wedding and the couple’s private relationship remain limited.
Her Children and Adult Family Life
Family profiles identify two sons, David and John, as the children of Judy Stewart Merrill and her husband. This made Jimmy Stewart their maternal grandfather. Public information about the sons is limited, so their education, careers, and present lives should not be treated as established facts without further evidence. Their names help explain the family tree, but they do not provide a complete picture of Judy’s experience as a mother.
Historical reporting places Judy’s adult family life in Northern California. Her father visited the Merrills in the Bay Area and spent time with his grandchildren. These visits show that family contact continued after she married and moved away from the home where she grew up.
Her Memories of Jimmy Stewart as a Father
Judy Stewart Merrill shared memories of her father in a museum podcast published in August 2016. The discussion covered his family relationships, friendships, and time in England for the London production of Harvey. These are useful subjects for anyone interested in the person behind his screen roles. They come from a daughter’s experience rather than from the characters audiences watched him play.
A photograph accompanying the interview shows Judy holding a poem found in a pocket of one of her father’s jackets. Small personal objects can add something that film awards and career lists cannot. In this case, the jacket and poem connect a public figure with family memory. The interview gives listeners a way to hear Judy’s own contribution to that history without assuming that every part of her life has been made public.
The Losses in the Stewart Family
The family experienced a major loss when Ronald McLean was killed while serving in Vietnam in 1969. He was a Marine lieutenant and Judy’s older half-brother. His death is an important part of the family’s history, especially because James had also served in the military. It belongs in an account of the Stewart children alongside their education, marriages, and other life events.
Judy later lost both parents within a few years. Gloria died in February 1994, after more than four decades of marriage. James died on July 2, 1997. These dates mark significant changes in the family, but they do not reveal Judy’s private thoughts or feelings. A biography can recognise the losses without inventing personal conversations or describing emotions she has not publicly shared.
Helping Remember Her Father Through Public Tributes
On May 20, 1995, Judy and Kelly represented their father at the opening of the museum dedicated to him in Indiana, Pennsylvania. James could not attend, so his daughters read a letter on his behalf. The occasion connected his family with the town where he had grown up. It also gave the sisters a direct role in sharing his message with the people gathered there.
Judy Stewart Merrill was also named alongside Kelly as a speaker for a centennial tribute scheduled for June 12, 2008, at the Samuel Goldwyn Theater in Beverly Hills. The event marked 100 years since their father’s birth. These two occasions show different parts of her public connection to his legacy: representing him during his lifetime and helping honour his memory after his death.
Her Connection to Charity and the Stewart Foundation
Older reporting describes Judy organising Bay Area fundraising events, including support for wildlife causes. Her parents attended some of these events. This gives her charitable work a place in the public record, though the reports do not provide a complete history of her involvement.
Public tax records also list Judy Stewart Merrill as a trustee of the Stewart Foundation, alongside Kelly and Gregory M. Paul. A trustee helps oversee a foundation, though a filing alone does not explain each person’s daily duties. The records provide evidence of a formal charitable role. They should not be used to guess her personal income, her working schedule, or the full extent of her involvement.
Her Career, Net Worth, and Life Today
Judy’s documented activities include charity work, family tributes, and speaking about her father. These give readers a clearer picture than a vague claim that she simply disappeared from public life. At the same time, the available evidence does not support a full career history. It does not establish a detailed professional timeline, a list of employers, or a personal business record.
Her personal net worth is also not reliably established in the material reviewed for this biography. Money held by a charitable foundation is separate from a trustee’s personal wealth. Her current home, routine, and plans are not described in the historical reports either. The most useful answer about her life today is therefore limited: the public record offers selected family and charitable connections, rather than a regularly updated account of her daily life.
Conclusion
Judy Stewart Merrill’s story brings a family perspective to the life of a much-loved actor. The strongest details concern her parents, twin sister, brothers, marriage, children, and recorded public activities. Her museum appearance, interview, and charitable role also show ways she has contributed beyond being identified as Jimmy Stewart’s daughter. Together, these facts provide a clear account of her background while leaving room for the parts of her life she has kept private.
