"Mackillop was born in Melbourne in 1842. Her parents had emigrated from Scotland, her father after leaving a seminary where he was studying for the priesthood. Mary worked as a teacher, but became increasingly aware of the need to provide better education across Australia – and in 1867, with this as its raison d'etre, she founded her order.The order went from strength to strength, attracting new recruits until her excommunication in 1871. She had to endure exile from the church (during which time she wasn't even allowed to wear her habit) for several months before being readmitted, and allowed to continue her work. And it was not until 2009, 100 years after her death, that Archbishop Philip Wilson of Adelaide made a public apology for her wrongful punishment.'
