In Paris Maxwell had met Mason Remey and Randolph Bolles who introduced him to the Baháʼí Faith. Later Maxwell married Bolles' sister May Ellis Bolles in London on 8 May 1902, and became a Baháʼí in 1909, after meeting ʻAbdu'l-Bahá, the son of the founder of the Baháʼí Faith. The Maxwell's home in Montreal became a centre of Baháʼí activity in Canada, and in 1912 ʻAbdu'l-Bahá visited their home. The Maxwells would frequently visit the Baháʼí World Centre in Haifa, Palestine (current day Israel).
