Diane Lou Oswald is best known to the public as the mother of Academy Award–nominated actor Woody Harrelson, but her own life is a story of quiet endurance. Long before her son became a Hollywood name, Diane was a young single mother in small-town America, raising three boys largely on her own after her marriage to a man who would later become one of the country’s most notorious contract killers. She never sought the spotlight, yet her steady, private strength is the foundation Woody has credited for the person he became.
This article brings together everything publicly known about Diane Lou Oswald — her early life, her marriage, her decades as a single parent, and the values she passed down — along with a timeline of the key events that shaped her family’s story.

Early Life and Family Background
Birth and Childhood in Lebanon, Ohio
Diane Lou Oswald was born in 1937 in Lebanon, a small town in Warren County, Ohio. Details about her exact birth date have never been made public, which is consistent with how she has handled her personal information throughout her life.
Her Parents, Kenneth and Mary Lou Oswald
Diane’s parents, Kenneth and Mary Lou Oswald, raised her in a household where community ties and traditional values mattered. Little else about her parents or any siblings has ever surfaced publicly, a reflection of how far outside the public record this branch of the family has remained.
Growing Up with Faith and Small-Town Values
Lebanon in the mid-20th century was the kind of town where neighbors knew each other and churches anchored community life. Diane grew up within that structure, and the discipline and faith she absorbed there would later carry her through the hardest years of her adult life.
Marriage to Charles Harrelson
How They Met and Married in 1959
In 1959, Diane married Charles Voyde Harrelson, a man who at the time worked as an encyclopedia salesman and moonlighted as a professional gambler. Charles was born in Lovelady, Texas, in 1938, making him roughly a year younger than Diane. To Diane, the marriage likely looked like the beginning of an ordinary family life.
Life Together in the Early Years
The couple had three sons together: Woodrow “Woody” Harrelson, Brett Harrelson, and Jordan Harrelson. For a brief period the family lived together, mostly in Texas, but the marriage began to strain fairly quickly as Charles’s absences grew more frequent and his associations more troubling.
Charles Harrelson’s Double Life and Criminal Path
Charles’s criminal record started well before his most infamous act. He was convicted of armed robbery in 1960 and was later tried for the 1968 murder-for-hire killing of Sam Degelia Jr., of which he was acquitted in 1970. His crimes escalated from there, culminating in the 1979 assassination of U.S. federal judge John H. Wood Jr. in San Antonio — the first killing of a sitting federal judge in the 20th century. Prosecutors said Charles was paid by El Paso drug figure Jamiel Chagra to carry out the shooting. Charles was convicted in 1982 and received two life sentences. He also briefly claimed involvement in the assassination of President John F. Kennedy during a standoff with police, a claim he later withdrew and one investigators found little evidence to support.
Separation and Divorce in 1964
Diane and Charles separated in 1964, when Woody was about seven years old. Their divorce was finalized that same year, well before Charles’s crimes became public knowledge — meaning Diane made the decision to leave the marriage on her own terms, not in reaction to scandal.
Life as a Single Mother
Raising Woody, Brett, and Jordan Alone
After the divorce, full responsibility for raising three young boys fell to Diane. She managed the household, the finances, and the emotional needs of her children essentially by herself, at a time when single motherhood carried far more social and financial hardship than it does today.
Her Career as a Legal Secretary
Diane supported her family by working as a secretary, with several accounts specifying she worked in a legal office. It was steady, unglamorous work, but it kept food on the table and gave her sons a sense of stability despite their father’s absence.
Moving the Family from Texas to Ohio
When Woody was around 12, Diane relocated the family from Texas back to her hometown of Lebanon, Ohio. The move brought the boys closer to extended family and gave them a fresh environment away from the fallout of their father’s growing notoriety.
Financial Struggles and Everyday Sacrifices
Woody has spoken candidly about growing up with very little money. Diane stretched a modest secretary’s salary to cover three children’s needs, and her sons have said they never doubted her commitment even when resources were thin.
The Role of Extended Family
Back in Ohio, Diane’s mother and grandmother became important figures in the boys’ upbringing. Woody has fondly recalled his great-grandmother Polly as lively and full of stories, while his grandmother was quieter and more reserved — two contrasting influences that rounded out his early family life.
Confronting Charles Harrelson’s Crimes as a Family
The Murder of Judge John H. Wood Jr.
The 1979 assassination of Judge Wood made national headlines and placed the Harrelson name at the center of a major federal case. Diane, by then years removed from the marriage, had to help her sons process the fact that their biological father was linked to a killing that shocked the country.
The JFK Assassination Claim
Adding to the family’s public burden, Charles’s brief and later retracted claim of involvement in JFK’s assassination kept his name — and by extension, his sons’ name — in the news for years afterward.
How Diane Shielded Her Sons from Bitterness
Rather than speaking negatively about Charles or forcing her own feelings onto her children, Diane let each son form his own opinion of their father. Woody has said that when he heard his father’s name mentioned on the radio in connection with a murder case at around age 11 or 12, his mother stayed calm and didn’t turn the moment into a tirade — a response that shaped how he handled the situation emotionally.
Charles Harrelson’s Death in Prison
Charles Harrelson died in federal prison in Colorado in March 2007 at age 68, after suffering a heart attack while serving his life sentences. By then, Diane had spent more than four decades as the primary — and far more stable — parental figure in her sons’ lives.
Diane’s Relationship with Woody Harrelson
Early Belief in His Potential
Woody has said his mother believed in him well before fame ever entered the picture, including taking pride in smaller milestones like his popularity at school.
Public Appearances Together
Diane has made rare public appearances alongside her son, including at the premieres of White Men Can’t Jump (1992) and Indecent Proposal (1993), and later at the Wimbledon Championships in London in 2017.
The Oscar-Nomination Note
One of the most repeated stories about their relationship involves Woody’s Academy Award nomination for The Messenger. Diane reportedly sent him a short note saying he’d “finally arrived” now that he was nominated alongside Christopher Plummer — a moment Woody has said meant more to him than the possibility of winning the Oscar itself.
The Values Diane Passed Down
Kindness, Respect, and Compassion
Woody frequently credits his mother with instilling basic decency — treating people with respect regardless of circumstance.
Work Ethic and Perseverance
Watching Diane work steadily through financial hardship taught Woody that consistency, not luck, produces results — a lesson he has referenced repeatedly when discussing his own career discipline.
Love for Nature and Simplicity
Diane’s appreciation for the natural world influenced Woody’s now well-known environmental advocacy and simple-living philosophy.
Faith and Presbyterian Upbringing
Diane raised her sons in the Presbyterian church, and Woody has joked he was involved enough in religion as a child that he could have become a minister. While his own beliefs shifted in college, he has never dismissed the role faith played in his upbringing.
Diane Lou Oswald’s Life Today
Staying Out of the Spotlight
Diane has consistently avoided interviews and media attention, even as her son’s fame grew. Her rare public appearances have been the exception, not the rule.
Her Role as Grandmother
Diane is grandmother to Woody and wife Laura Louie’s three daughters — Deni, Zoe, and Makani Harrelson.
Life in Maui, Hawaii
Woody and Laura have raised their family in Maui, maintaining the same preference for privacy that has defined Diane’s approach to life for decades.
Her Other Sons — Brett and Jordan Harrelson
Brett Harrelson’s Acting Career
Brett Harrelson has appeared in various acting projects over the years, occasionally sharing the screen with his brother, though he has kept a far lower public profile than Woody.
Jordan Harrelson’s Film Projects
Jordan Harrelson has worked on productions including Between the Stars, Well, and Broken Promise, again largely away from mainstream attention. Notably, Brett and Jordan participated in a 2020 podcast investigation, Son of a Hitman, revisiting their father’s case — an project Woody chose not to be part of, reportedly out of respect for how private he and his mother prefer to keep the subject.
