I recently found a site on the web called Ex-Classics which has an online copy of "The Newgate Calendar".

This work is a record of famous criminal cases from British history (cases from it were serialised on BBC Television in the 1960s) including the following, which may have some interest to students of folk song.

. Gilderoy
. Captain Kidd
. Jack Hall
. Dick Turpin

There are no doubt many others!
