When They Married
According to Hamill’s official biography, the couple married in 1978. In an April 2018 report, ABC News reporter Clayton Sandell wrote that the couple had been married for 40 years and were expecting to mark their anniversary that December. That “40 years” figure was accurate as of 2018. It is a historical detail, not a current count.
Their Three Children
Hamill and Marilou have three children:
- Nathan, whom Hamill identified as the couple’s first child in a 2020 StarWars.com interview
- Griffin
- Chelsea
The biography and ABC News both list the same three names, which is the basis for the family count stated here.

Family Life Away from Hollywood
In her 2018 conversation with ABC News, Marilou described a quieter routine than the typical Hollywood social calendar. She said: “We don’t live in town, so we don’t go in and do all the party circuits.” The remark offers a sense of how the family has tended to live, though it is one interview from one point in time.
Hamill has also spoken about the start of the family. In the 2020 StarWars.com interview, discussing the filming period for The Empire Strikes Back, he said: “It was a really pivotal time in my life because [my wife] Marilou and I were expecting our first child.” That quote places the arrival of their first child around the time of that film’s production.
The Malibu Home
A 2025 Los Angeles Times profile by Josh Rottenberg reported that Mark and Marilou married in the backyard of their Malibu home and raised their three children there. The same report said the house was uninhabitable after the January 2025 fires in the area. That is a description of conditions as reported in June 2025, not a current status update. Readers looking for the home’s present condition should check more recent reporting.

The core facts are well documented: her name, the 1978 marriage year, and the three children’s names come from Hamill’s official biography and are repeated in ABC News coverage. Details about her private life beyond these reports, including her career and personal background, are not covered by the sources used here, so this article does not speculate on them.
