It’s interesting to read about the crimes committed in the past by ancestors; some so strange and others you don’t even want to ponder. But among these are the many that found our ancestors on Australian shores for 7 years or more; such as stealing a shirt, breaking and entering, machine breaking and even poor morality.
Convict women were often punished for having poor morality. In 1838, Convict women at the Cascades Female Factory reacted by mooning the visiting governor and the reverend. (http://www.convictcreations.com/history/crimes.htm)
