So, the most we can say is that she was born about 1773 and (apparently) in Suffolk.
The Suffolk Burials Index indicates that her maiden name was not that uncommon. But there is only one entry in Herringswell (James Prick, buried12 June 1748, age unknown) which makes me think that she came from elsewhere.
Have you checked the marriage register/banns? This will tell you where she was living in 1792 and witness names may also provide a clue.
