Whats in a name?

Billie or Billy & Charlie, Charly or Charley?

There has been little agreement over the names to be used. Examination of articles published over the last thirty years shows a fairly random use of the above spellings. Nineteenth century documents, however, consistently use Billy & Charley, the earliest use being the Times report (6 August 1858) of the trial at Guildford, when their names are first reported.
