Though she was NOT a member of a secret society she was given a Masonic deploma......she also dabbled in Kabala.....and had Masonic friends/contemporaries.
However, my main point is there were MANY others at that time who were heavly influenced by each others leanings during this esoteric revival. Esoteric in many circles is also used to describe the occult or can be used as a different way of thought. Again there were MANY/VARIOUS KINDS of esoteric thought, one can liken that time to our 20century ......new age.....kabala.....Tarot....Wicca......buddhist....etc.. Dalai Lama even pratices magic. Budhists use various occult methods to assist in finding reincarnated beings........
