From the Criminal Register it appears that was Mary CULLINGFORD's third conviction, hence the transportation.
The case was heard at Portsmouth Borough Sessions and the Hampshire Chronicle Monday 09 April 1838 reported that the 'blanket & c.', the property of John EDWARDS, was stolen at Portsea. There are several of his name in Portsea in 1841: do you have any idea of his trade?
Unfortunately the British Library Newspaper Archive OCR presented problems, not only from the original hyphenatiion of Mary's surname, which is why it took me a while to locate the Chronicle report and make a load of necessary corrections. If I persevere, it may be possible to locate other newspaper reports, but don't hold your breath! If you'd like a copy of my transcription, please PM me with your email address.
If Mary had any dependent children it is likely they would have been repatriated to their respective Poor Law Union of parishes of origin. I've not encountered anything that records Mary a widow.
Happy hunting!
