Hi Roecoyle
If you follow the above link to the National Archives then take the link named electronic catalouge then click on Online Public Access Catalogue (OPAC) there is a search facility which has some brief index info on some indictments and other cases held at the archive ....I found my great gran had got two months for an acid attack on her soon to be husband....!!!!
It, as ever, depends on how unusal the name you are looking for .....
Best of luck
