Diane Lou Oswald is the mother of actor Woody Harrelson and the former wife of convicted contract killer Charles Harrelson. She is not a public figure herself. She worked as a secretary and legal assistant, raised three sons, and has stayed mostly out of the spotlight. This Diane Lou Oswald biography explains what reliable sources confirm, what is still unclear, and which online claims you should ignore.

Who Is Diane Lou Oswald?
Diane Lou Oswald is an American woman from Lebanon, Ohio. People search for her because of her son Woody, the Oscar-nominated actor known for Cheers, True Detective, and The Hunger Games. Her own life was ordinary in public terms, but her story is tied to some very dramatic events in her family.
One important clarification: she is not the mother of Lee Harvey Oswald. A few low-quality websites make that claim, but it is wrong. Genealogy records show that Lee Harvey Oswald’s mother was Marguerite Claverie Oswald. A shared surname does not mean the two families are close relatives.
Early Life and Family Background
Diane grew up in Lebanon, a small town in Warren County, Ohio. Several sources name her parents as Kenneth Oswald and Mary Lou Oswald. Local news reports, repeated by secondary websites, say she graduated from Lebanon High School in 1955. That detail also fits the 1937 birth year, since she would have finished school at about 18.
Her exact birth date has never been made public, so her age in 2026 is an estimate. Most sites say she is around 88 or 89. I could not find an official record to confirm this, so treat it as approximate.
Marriage to Charles Harrelson
According to Wikipedia, Diane married Charles Voyde Harrelson in 1959, and they divorced in 1964. One other website gives the wedding year as 1958, so the exact year is not fully settled. They had three sons: Jordan, Woody, and Brett. Woody was born on July 23, 1961, in Midland, Texas.
Charles later became known for serious crimes. He was convicted of murder in 1973 and was later convicted of killing federal judge John H. Wood Jr. in 1979. He died in prison in 2007. Woody has said his father left the family home in Houston in 1968, which means Diane was raising the boys on her own for most of their childhood.
Raising Three Sons and Moving Back to Ohio
Woody’s biography says the family was poor and depended on his mother’s wages. In 1973, Diane’s family moved to her hometown of Lebanon, Ohio. Woody finished Lebanon High School in 1979, and his brother Brett was also raised there.
Family help likely mattered too. Woody has talked about being raised by strong women, including a grandmother and great-grandmother, along with his mother. This part comes mostly from interviews, so it is best read as Woody’s own memory, not as a documented record.
Diane Lou Oswald’s Work Life
Diane worked in office jobs and later in the legal field. Major profiles of Woody call her a secretary. Other sources use the more specific words “legal secretary” or “legal assistant.”
Secondary websites also say that Dayton Daily News reported she worked as a legal assistant at a law firm in Franklin, Ohio. I could not open the original article, so I am treating that detail as reported, not fully verified. What is clear is that her job paid modestly, and her income supported the family.
Faith and Values
Diane is described as a devout Presbyterian. Woody was raised in a Presbyterian home, and he has joked that he might have become a church minister if life had gone differently. Later in life he became known for his interest in nature, peace, and kindness, and he has linked some of those values to the way his mother raised him. Some websites add many extra claims about her “activism,” but I found no reliable source for them, so I left them out.

Her Public Life Today
Diane has appeared next to Woody at a few public events, such as Wimbledon in 2017, but she does not seem to seek attention. I found no verified social media accounts and no recent interviews with her. Websites that describe her daily life, current address, or health in 2026 are mostly guessing, and I chose not to repeat those claims out of respect for her privacy.
What Is New in 2026?
There is no major personal news about Diane herself in 2026. The new attention comes from her son’s work. On September 23, 2026, Apple TV released Brothers, an eight-episode comedy starring Woody Harrelson and Matthew McConaughey as fictional versions of themselves. The show plays with a real rumor. In 2023, McConaughey said his mother knew Woody’s father around the time he was conceived, so the two actors joked that they might be half-brothers.
This rumor is about Charles Harrelson, not Diane. I found no publicly confirmed DNA result, so the question remains unproven. The series airs weekly until November 4, 2026.
Facts vs. Rumors: What Online Articles Get Wrong
Many pages about Diane Lou Oswald repeat each other and add details that cannot be checked. Here are the most common problems.
- Net worth: Some sites list a figure such as $500,000, but they give no source. No reliable net worth is known, so I do not use one.
- Lee Harvey Oswald link: Some pages claim she is his mother. This is false.
- “Civil rights activist” claims: A few pages describe her as an activist and craftswoman. I found no trustworthy source for this.
- Height, weight, and exact age: These appear on many sites without any source, so they should not be trusted.
How This Was Researched
I researched this biography by reading public biographies of Woody Harrelson, Wikipedia entries on the Harrelson family, recent entertainment news, and about ten existing articles that rank for this name. Most of those articles repeat the same few facts, and many mix in unsourced claims, so I checked key dates against more than one source and marked every unclear point. This article tries to fill the gap by showing what is confirmed and what is not, and by clearing up the common mix-ups.
