She was the daughter of the Theosophist, Secularist, and Co-Freemason Annie Besant[4] and her husband Rev. Frank Besant. She had an older brother named Arthur Besant. When her father and mother separated, she was to be under the custody of her mother, but in 1878 her father went to the High Court and won the case for custody. It was not until she was 21 that she returned to her mother.[5]
After her mother's death, Mabel Besant-Scott briefly became the head of the British Federation of Co-Freemasonry and held the highest thirty third degree in Scottish Rite Freemasonry.[8] In 1933 she visited India where her mother died and met the Avatar Meher Baba, where they discussed her mother resurrecting as a man in India.[9] She wrote several articles for The Adyar Bulletin, a periodical of the Theosophical Society based in Adyar, India.[10] A year later she abruptly resigned from Co-Freemasonry,[3] joining the Rosicrucian Order Crotona Fellowship shortly afterwards and taking with her some of her followers from Co-Masonry. She was one of the most active members of this Rosicruciantheatre near Christchurch, which was led by George Alexander Sullivan.[11]
