John Murgatroyd Hubbard (1839 - 29 October 1899 ref**) was a convict transported to Western Australia, and later became one of the colony's ex-convict school teachers.
Born in 1839, Hubbard was working as a clerk in 1863 when he was convicted of forgery and sentenced to twenty years' penal servitude.
After receiving his ticket of leave, he worked for Daniel Connor for a while, then briefly taught at Wicklow school.
During this time he also employed other ticket-of-leave convicts to dig out sandalwood stumps from land that had been previously cut over.
Hubbard died in hospital from the effects of poison, a Coronial Inquiry held on 7 November 1899 by Acting District Coroner Dr E Black, found the cause of death was asphyxia caused by strychnine that was administered by the deceased.
