Mary Helen Mackillop was born in Melbourne, Australia in 1842 and died in 1909. She founded the Sisters of St Joseph of the Sacred Heart, a religious congregation that established many Catholic schools across Australia. Mary came from a large family and had seven siblings. She started her first school in a stable in Penola, South Australia in 1866 to provide education to isolated communities. Mary faced opposition from the church but persisted in her mission to expand educational opportunities, especially for poor children.
