In 1943 on advice from the Ouija board, Cooke married Wilma Dorothy Vermilyea. Millen Cooke, as she became known, was a poet, writer, and occultist who had a poem published in 1936 in
Weird Tales, but was most active between May 1946 and May 1950, with stories and essays appearing in
Amazing Stories,
Fantastic Fiction, and
Other Worlds Science Stories. She had written a number of letters to
American Theosophist in the early 1940s. John Starr Cooke was also published in
American Theosophist in August 1945 with a story called "Black Magic Question Mark". In 1944 John's father Clarence Hyde Cooke died, and John and Millen Cooke traveled the world, including a mission to go as far north and as far south as possible. On these travels, John Cooke met an assortment of gurus, mystics and spiritual figures, including
Meher Baba. Cooke also studied medieval Tarot decks in museums, and spent considerable time living in London. Millen Cooke had a series of visions which John Cooke drew and was later known as the Atlantean Tarot (published 1992). In 1948, John Cooke learned that
Meher Baba was seeking to establish an ashram in California, and he assisted the group to purchase
Meher Mount in the
Ojai Valley. In 1950 a pregnant Millen Cooke (and with John denying paternity) read
Dianetics by
L. Ron Hubbard, first published in Astounding Science Fiction in May 1950. Millen Cooke was so enthusiastic about the ideas she encountered that she flew at once and alone to New York. John was enraged to find his wife had left and drove virtually non-stop for a day and a half to find her. In New York Cooke quickly became a master of the techniques given in Dianetics, and subsequently met
Mary Oser, who had flown to New York from Switzerland seeking a competent practitioner of Dianetics to treat her husband. Mary Oser (née Wilbur) had attended
Reed College in Oregon where she met fellow student
Peter Oser, a great-grandson of
John D. Rockefeller. They were married after he had proposed several times and they relocated to the Oser family's home city of
Basel, Switzerland. Soon after John Cooke met Mary Oser he returned with her to Switzerland and lived with the Oser household in Basel, practicing the methods of Dianetics. Peter Oser became a blind follower of John Cooke. In December 1950 the Oser family moved suddenly to central Africa, led by Cooke and his communications with the Ouija board. In 1951 John Cooke and Millen Cooke were divorced, and their daughter Valerie Melza Cooke was born. Around this time, Peter Oser and Mary Oser were also divorced. In 1952 John Cooke married Mary. ==Northern Africa ca. 1952–1956==
