Her father, John Samuel Langley was English. Born in 1889, he came to Australia in 1912. After arriving in Perth he became a schoolteacher and took up public soapbox lecturing. He was atheist and an impressive speaker. The Victorian Rationalist Association became aware of him and invited him to Melbourne - an invitation he accepted. The Association was founded in 1906. Its fundamental view was that all significant beliefs and actions should be based on reason and evidence. It aimed to promote critical enquiry into religion and what it perceived as other superstitious practices, stimulate freedom of thought, and encourage interest in science, criticism and philosophy. In 1919 he became the Associations Secretary. In 1924 he founded the Rationalist Journal, and in 1926 he became the inaugural Secretary of the Rationalists Society of Australia. Margaret's mother was Vera Lucy Savige. She was born in Elsternwick in 1892 and met Jean's father through the Society. She was already a Society member, and at the age of twenty-two, on their Board of Directors. They married and lived on a Rationalist commune at Mentone. Several families lived there, on a ti-tree covered ten-acre property by the sea.
