Hello Eumungerie,
I notice that in 1847, your Obadiah was in trouble for stealing potatoes, a crime that had him sentenced to 7 years penal transportation, and that at his hearing, the judge mentioned another matter that was in trouble for (previous convictions in other words). Are you aware of this matter? In 1844, he would have been 28, the report of 1847, says he was 31 then.
The Derby Mercury Wednesday, March 6, 1844
Obadiah Berrisford & Joseph Berrisford of Ashover were both charged with stealing two hen fowls, two ducks and one drake, the property of Thomas Siddal and one spade the property of James Else.
Also, in the same newspaper: The Derby Mercury,Wednesday, November 1, 1843
Joseph Berrisford, pauper in the Chesterfield Union Workhouse, was committed to 2 months hard labour for assault on Thomas Huckins.
I will send PM for his trial in 1847, just in case you don't have it.
Tom
