Hungerford was born near Cork to Captain Emanuel Hungerford and Catherine Loan(e). The family migrated to New South Wales in 1828, and his father settled on the Hunter River. Hungerford became a pastoralist, owning property near Walgett and inheriting his father's Hunter property in 1852. On 19 June 1852 he married Emma Hollingsworth Wood, with whom he had nine children; a second marriage to Catherine Mary Mallon produced six children.
