Hi Justine,
Was this Janet Fisher m.s. Thomson? If so, there are entries on the National Archives of Scotland site for her dated 1874 and 1876, both for the crime of theft and previous convictions (probably including her time during 1868).
In 1874, she was 28 and staying at Union Street, Maxwellton, Dundee.
In 1876, she was 29 and staying at Nethergate, Dundee.
