Career
Known as a writer on the Romani people, he also published a religious work. Hoyland has been described as "of Sheffield, Yorkshire", and as "formerly of York". In the summer of 1814 he began to study the Romani of the East Midland counties Northamptonshire, Bedfordshire, and Hertfordshire, and their poor economic state.
He carried out extensive survey work, and sought to draw attention to his perception that the Romani needed religious conversion, as well as a better standard of living.
A sympathetic observer, Hoyland also supported forced education of the Romani. Hoyland died at Northampton on 30 August 1831.
