ABOUT POST
Her rebellious nature was mainly driven by resentment at the abuse she suffered as a child and her experience in a Dublin reformatory.It was music that rescued her, unleashing a creative talent that made her a worldwide music star - but also a rebel prepared to be controversial and never play the game of being an image-led pop star.
With her elfin features and skinhead look she was one of pop music's most recognisable figures.
Sinéad Marie Bernadette O'Connor was born on 8 December 1966 in the affluent Glenageary suburb of Dublin.
She was the third of five children of Sean O'Connor and his wife Marie. The couple had married young and their relationship, often stormy, ended when O'Connor was eight.
Her brother, Joseph, once described their mother as deeply unhappy and disturbed and prone to physical and emotional abuse of her children.
O'Connor eventually moved out to go and live with her father but she often played truant to go shoplifting.
