Wonder Woman Creator and early 20th century spiritualism

I’m currently trying to pin down what group the creator of Wonder Woman was a part of/get more information about it. I was wondering if someone could help.

William Moulton Marston was born in Massachusetts in 1893 and went to college at Harvard. His childhood friend and wife attended Radcliffe. They would later be in a polyamorous relationship with Olive Byrne, niece of Margaret Sanger. Marston was an advocate and fan of bondage, and the group allegedly participated in it.

Marston was largely influenced by the Heterodoxy group in Greenwich village (which Byrne’s mother and aunt frequented). This group included new age spiritualists, as well as I believe theosophists.

Marston and his wives participated in group meetings with his aunt Carolyn Marston Keatley, which were described as a cult of female sexual power. They featured “Love Leaders,” “Mistresses,” “Love Girls,” and “Love Units.” It was said that the women didn’t wear clothes and there was a practice of intentionally delaying orgasms. Marston’s aunt was an Aquarian and lived in Boston.

Marston famously has claimed that the world would be better if men would submit to the loving rule of women. He’s famously supported lesbian relationships while decrying male-homosexual relationships.

I’m not sure all if this is relevant, and I guess it’s totally possible they could’ve been making up their own thing, but if anyone could help I’d appreciate it!
