From the Conduct Records: STEVENS Grace - Rajah, 24 July 1841. Transported for Stealing a Gown Print. Gaol report convicted before a prostitute. Single. Stated this offence stealing a gown piece once for same 3 months. 2 months on the town. Single. Surgeons report Quiet.
Feby 17th 1843 Archer/misconduct in being with Isaac KITT for improper intercourse 6 mths hard labour in the factory, Launceston. The next bit is very hard to read, and at the end says TL 4/11/45 (Ticket of Leave, 1845)
You could be accused of being a 'prostitute' at that time, if you were, say, in town without a chaperone. As a servant girl from a poor mining family, Grace was possibly often placed in a position where she had no choice.
Improper intercourse was probably just 'talking to' - but was against the rules for house servants.
I believe the scar on the thumb is an indicator of a criminal record.
