The couple married 13 February 1813 in England. William and Elizabeth's family, including Elizabeth's widowed mother, Sarah Baldwin, came to the Colony under Thomas Peel's ill-fated settlement scheme. The scheme collapsed soon after their arrival and like many others indentured to Peel, the Devenish's were left stranded on the beach at Clarence for nearly a year until Governor Stirling came to their aid. The Devenish's took up Stirling's offer of land at Guildford where they settled early in 1831, establishing a small farm on allotments 32 and 33 in James Street, near the corner of East Street. They were freed from their indentures in 1832. The family built a cottage and planted fruit trees, grape vines and vegetables, and a small crop. In 1835 they established an inn at the premises and commenced brewing beer that soon became known for its excellence. By this time they had also been granted a small holding near Beverley, overlooking Wittenoom's Gwambygine Estate on the Avon River. The Devenish's Inn became a meeting place for the Agricultural Society and the Guildford Trust. The inn and adjacent grounds were used for a number of years for the agricultural fair, the forerunner of the Royal Show. William died 10 April 1854 at Guildford. After William's death, the inn and brewery were taken over by his youngest and only surviving son Henry, who, in 1860 built a larger house on the property and established a shop and bakery on the site. His sister, Elizabeth married Ben Robins in 1838 and they farmed at Guildford and Beverley. Elizabeth Devenish died 8 January 1863 at Guildford, some twelve years after her mother, Sarah Baldwin.
