moved to London, where he became an associate of Toynbee Hall, the world's first university settlement. The 1901 census shows him lodging at the hall of residence, Balliol Hall, Whitechapel, and employed as an assurance society clerk. He was also involved with the labour reform movement in Britain and wrote articles for various publications. In 1904 he married Mary Ann Walker of Kinsale, and in 1907 the couple moved to Vancouver, British Columbia, Canada. In 1916 he was back in Britain and joined the army. In Canada he had been involved with property finance but also started a lumber business; his experience of working with heavy equipment made him a suitable candidate for the Royal Army Service Corps.

In the late 1920s he invested money in the Mandrake Press and associated with the English occultist and novelist, Aleister Crowley. They both had a relationship with a young lady called Deirdre Patricia Maureen Doherty, with whom Crowley had a child.
