Hello Annie,
Sorry, and my apologies, I thought you may have been misled with John Treadgill who was not transported but "Released on Licence" back into England.......any of the Parkhurst Boys in this category, or those whose sentences had expired and were simply discharged from Parkhurst Prison, are going to be extremely hard to find. The three examples I sent you earlier are all in these categories.
The only true hope is that I concentrate on those with particularly unusual names or, another thought, some were returned to the Gaols where they had originally been imprisoned after conviction.
The difficulty with the Parkhurst Prison Register that I use, and most other researchers have the same problem, is to determine whether or not the age quoted is that either when they entered the Prison or were discharged. I tend to use the former........in most cases, however, there is only a 2 year, or at the most 3 year, age difference between the two events.
William Isherwood was transported and the records I have from Australia indicate there is every possibility he returned to England, although it would have been extremely expensive.
Once again I really am grateful for the way people "mucked in" to help me.
For now
Tony
