In 1905, Roche and Caroline moved with Mazo's parents to Acton, Ontario to operate the Acton House hotel. She was known locally as "Maisie Roach", and lived there until 1908, selling one of her stories while she was there. Her novel "Delight" was based on her time there, and Acton's geography figures notably in "Possession". A few years later in 1911, by now in her early thirties, de la Roche moved with Caroline and the Roches to Sovereign House in Bronte, Ontario, to try life as farm owners. By now, de la Roche had resumed writing and was placing stories in American magazines on an occasional basis.
