William Moulton Marston, creator of Wonder Woman, psychologist, inventor, and polyamorist, with his family. Marston is seated in the center, that’s Olive in the white blouse behind his shoulder, Elizabeth is in the right corner looking sideways at the camera, and the girl on Marston’s knee is the daughter named after Olive. The woman with the square jaw in the left corner is someone named Marjorie Wilkes. Maybe she was a third woman in the Marston family? She was an assistant who worked on the comic.

"The psychologist’s superheroine was at least partly inspired by his wife, Elizabeth Holloway Marston, but there were actually two Wonder Women in the family. Marston wasn’t just kinky, he was a polyamorist.
The clues are in Marston’s interviews with “Family Circle,” conducted by a young woman named Olive Byrne, who was in fact, the aforementioned interviewer Olive Richard. Though he refers to Byrne as “my Wonder Woman” and claims her “Arab ‘protective’ bracelets” were the inspiration for the ones worn by the Wonder Woman character, Byrne herself never disclosed to readers that she was romantically involved with her subject. In fact, Byrne was a former student and research assistant who moved in with Marston and his wife in the late ’20s and subsequently bore him two sons. The exact nature of the women’s relationship is not known, but it’s clear that they were very close. Not only did the two know about each other and raise each other’s children, Elizabeth Marston formally adopted Byrne’s children as her own and even appears to have named her daughter after Olive.
While Olive Byrne may have provided the physical inspiration for Wonder Woman, Elizabeth Marston was an Amazon in her own right, getting degrees in psychology and law, putting herself through school and working to support the family for thirty-five years. “Olive stayed home with the kids, while Mom continued to work,” said Elizabeth’s son Pete. “It was a wonderful situation, a win-win deal for everyone.” Indeed, by all accounts Marston’s unconventional family was a happy one. “It was an arrangement where they lived together fairly harmoniously,” said Marston’s son Byrne to biographer Les Daniels. Sheldon Mayer, who became a family friend, remembered Marston as “the most remarkable host, with a lovely bunch of kids from different wives and all living together like one big family - everybody very happy and all good, decent people.”
Unfortunately, Marston was unable to enjoy his happy home life for long, as he first contracted polio and then succumbed to cancer in 1947, reportedly continuing to write from his deathbed. After Marston’s death, his widows continued to live together for another four decades until Olive’s death in the late eighties. As Byrne Marston described it, “It’s kind of crazy, but it worked out and they got along quite well. They were just a pair from then on until they died.” Elizabeth Marston died in 1993, at the age of 100.”
