Diane Lou Oswald: Woody Harrelson’s Mother, Life and Family 

Diane Lou Oswald is best known as the mother of Hollywood actor Woody Harrelson. Born into an Ohio family and closely linked with Lebanon, she worked as a legal secretary and raised three sons after her marriage to Charles Voyde Harrelson ended. Her sons are Woody, Brett Harrelson, and Jordan Harrelson. Diane lived largely as a private citizen rather than an entertainment figure. Her family history attracts attention because Woody became an Academy Award-nominated actor, while Charles developed a notorious criminal history. Diane’s Presbyterian faith, parenting, work life, and influence on Woody form the clearest parts of her documented biography.

Who Is Diane Lou Oswald?

Diane Lou Oswald, also known as Diane Harrelson, is an American mother and former legal secretary from Lebanon, Ohio. She became publicly known through her family rather than through a career in Hollywood.

She and Charles Voyde Harrelson had three sons. Woody Harrelson entered the entertainment industry, while Brett Harrelson also worked as an actor. Jordan Harrelson has maintained a much lower public profile. The family’s roots connect strongly with Warren County and Lebanon.

Diane Lou Oswald vs. Diane Harrelson

Diane Lou Oswald is her maiden name. Diane Harrelson reflects the married surname she used after marrying Charles Voyde Harrelson.

Both names appear in biographical records connected with Woody Harrelson and the Harrelson family.

Why Diane Lou Oswald Attracts Public Interest

Most public interest comes from her relationship with Woody Harrelson, an Academy Award-nominated Hollywood actor.

Her biography also connects parenting, family history, Charles Harrelson’s criminal record, and Woody’s upbringing. Unlike many celebrity relatives, Diane remained a private individual outside the entertainment industry.

Diane Lou Oswald’s Early Life and Family Background

Diane came from Lebanon in Warren County, Ohio. Her early years were rooted in the American Midwest, where church, community life, family responsibility, and traditional social structures shaped many households during the 1940s and 1950s.

Her birth year is reportedly 1937. That places her childhood in the period following the Great Depression and during World War II and post-war America.

Her Parents: Kenneth Oswald and Mary Lou Oswald

Diane’s parents are identified as Kenneth Earl Oswald and Mary Lou Lauterwasser Oswald.

Her Ohio family background is associated with hard work, religion, and small-town community life. These values later appeared in descriptions Woody gave of his mother and upbringing.

Education and Lebanon High School

Diane reportedly graduated from Lebanon High School in 1955.

The school connection supports her longstanding ties to Lebanon, the same Ohio community where her sons later spent important years of their childhood. Her education preceded her work in secretarial and legal-office settings.

How Old Is Diane Lou Oswald? Birth Date and Age Verification

Diane Lou Oswald was reportedly born in 1937. An exact public birth date has not been firmly established.

Her reported 1955 graduation from Lebanon High School fits that general timeline. As of 2026, a 1937 birth year would place her in her late 80s.

Diane Lou Oswald’s Career as a Legal Secretary

Diane worked as a legal secretary, a profession requiring organization, accurate paperwork, confidentiality, and regular contact with attorneys and legal documents.

The work provided steady income while she supported three sons. Secretarial employment also required careful handling of meetings, court documents, correspondence, and confidential information.

Her specific employers and complete professional résumé are not widely documented. Her legal-secretary career is nevertheless one of the most consistently reported facts about her working life.

Diane Lou Oswald and Charles Voyde Harrelson

Diane married Charles Voyde Harrelson in Pasadena, Texas, on February 26, 1958. Baptist Rev. L. D. Morgan performed the ceremony.

By 1959, the couple were married and beginning family life. Their marriage ended in divorce in 1964 after several difficult years.

When Did Diane Lou Oswald Marry Charles Harrelson?

The Texas State Historical Association records the marriage date as February 26, 1958.

The ceremony took place in Pasadena, Texas. Charles Harrelson later worked in jobs that included selling books and repairing dental equipment, although gambling increasingly became part of his life. 

Why Did Diane Lou Oswald and Charles Harrelson Divorce?

Diane and Charles divorced in 1964.

Their marriage had become unstable as Charles’s gambling and criminal behavior grew more serious. Diane then carried the main responsibility for raising their three sons.

Charles Harrelson’s Criminal History and Its Impact on the Family

Charles Harrelson built a criminal history involving armed robbery, murder cases, gambling, and later murder-for-hire notoriety.

He was convicted of armed robbery in 1960. His most famous case involved the 1979 killing of U.S. District Judge John H. Wood Jr. in San Antonio. He ultimately received two life sentences and died in federal prison in 2007. 

For Diane and the children, his absence shifted parental responsibility toward their mother and extended family.

Diane Lou Oswald as a Single Mother of Three Sons

Diane became the central parent for Woody, Brett, and Jordan.

Her legal-secretary income supported household expenses, food, clothing, schooling, and other daily needs. Extended family also helped create a more stable environment.

Woody later described his childhood as strongly matriarchal and credited his mother with shaping his respect for people and the world around him. 

Moving Back to Lebanon, Ohio

The family eventually settled in Lebanon, Ohio, where Diane had grown up.

Woody moved there around the start of his teenage years and attended Lebanon High School. The move brought the boys closer to Diane’s family support system and Ohio community connections.

Support From Her Mother, Grandmother, and Extended Family

Diane did not raise the boys in complete isolation.

Woody has described a household shaped by his mother, grandmother, and great-grandmother Polly. These multiple generations created the matriarchal family dynamic he later discussed publicly. 

Diane Lou Oswald’s Children and Family

Diane and Charles had three sons: Jordan, Woody, and Brett.

Each followed a different path. Woody became an internationally recognized actor, Brett entered acting and production work, while Jordan stayed largely outside celebrity publicity.

Woody Harrelson

Woodrow Tracy Harrelson was born July 23, 1961, in Midland, Texas.

He studied English and theatrical arts at Hanover College before building a major acting career. His role as Woody Boyd on Cheers brought television fame, while films such as The People vs. Larry Flynt and The Messenger earned Academy Award recognition. 

Brett Harrelson

Brett Voyde Harrelson was born June 4, 1963, in Midland.

He became an actor and producer, appearing in projects including The People vs. Larry Flynt. Brett also attended Lebanon High School and later worked as a legal clerk before pursuing entertainment work. 

Jordan Harrelson

Jordan Kenneth Harrelson is Diane and Charles’s eldest son.

Unlike Woody and Brett, Jordan has kept a private life with little sustained public attention. He remains part of the immediate Harrelson family but has no comparable Hollywood profile.

Diane Lou Oswald’s Influence on Woody Harrelson

Woody has repeatedly described Diane as a major influence on his upbringing.

He has connected her with compassion, responsibility, honorable behavior, and respect for other people. Her influence came mainly through parenting and example rather than direct involvement in his Hollywood career. 

What Woody Harrelson Has Said About His Mother

In interviews with outlets such as The Guardian, Woody has described his mother as highly influential.

He credited her with teaching respect and good values and called her a strong role model. His comments in GQ, People, Esquire, and other profiles also connect his childhood with a strongly matriarchal home. 

Did Diane Support Woody Harrelson’s Acting Career?

Diane supported Woody as his mother, but there is no clear evidence that she managed his acting career or made professional decisions for him.

Woody built his career through theater, television, and film after completing college.

Faith, Values, and Religious Upbringing

Religion formed a visible part of the Harrelson household.

Diane was a devout Presbyterian, and church attendance helped shape family life. Woody later attended Hanover College, a Presbyterian institution in Indiana, after growing up with a strong spiritual foundation. 

Raising Her Sons in the Presbyterian Faith

Diane raised her sons within the Presbyterian Christian tradition.

Church attendance, prayer, Bible study, sermons, and religious teaching formed part of Woody’s childhood. He even showed an early interest in ministry before choosing another path.

Compassion, Work Ethic, and Moral Values

Woody has linked his mother with compassion and a strong work ethic.

He has also credited her with lessons about integrity, respect, responsibility, and honorable behavior. These values remained part of how he described her decades later. 

Nature and Environmental Values in Woody Harrelson’s Upbringing

Woody later became known for environmental activism, including concern for forests, sustainability, and climate issues.

His work has included activism and projects such as Kiss the Ground. He has also connected his mother with respect for the world and nature, although his adult environmental positions developed through his own experiences and activism. The Guardian

Is Diane Lou Oswald Related to Lee Harvey Oswald?

The shared Oswald surname has caused confusion. Lee Harvey Oswald’s documented family line includes Robert Edward Lee Oswald Sr. and Marguerite Frances Claverie, not Diane’s parents Kenneth Oswald and Mary Lou Oswald.

Diane has maintained a private life for decades.

Lebanon, Ohio, remains central to her biography, but precise current residence and health details are not established public facts. She has occasionally appeared publicly beside Woody despite avoiding a regular media profile.

Is Diane Lou Oswald Still Alive?

Diane was publicly photographed with Woody at Wimbledon in London on July 15, 2017.

That documented appearance confirms she was alive at that time. More recent verified information about her current status remains limited. 

Latest Verifiable Public Appearance or Record

Diane Lou Oswald’s Net Worth and Financial Claims

No reliable public financial record establishes Diane Lou Oswald’s net worth.

Her known career was as a legal secretary, and accounts of the family describe modest finances during her sons’ childhood. Precise claims about assets, wealth, salary, or a celebrity-style net worth should therefore not be treated as established facts.

Verified Facts vs. Unverified Claims About Diane Lou Oswald

Firm facts include Diane’s marriage to Charles Harrelson, their 1964 divorce, their three sons, and her work as a legal secretary.

Claims about exact height, weight, body measurements, wealth, current health, and precise current residence do not have comparable public documentation.

Claims That Need Caution

Exact birth date, exact age, net worth, health, present residence, remarriage, siblings, and detailed employment records are not firmly documented.

The same applies to physical measurements often attached to celebrity biography profiles.
