Hi Stan
Thanks for this info and the scan of the document.
I think it does read 7 years penal servitude (I had thought the red cross meant it had been crossed out). I think it also said he had a former conviction of felony, so this would explain him getting police supervision as well, which would follow completion of sentence.
Would Chatham have been the prison this John Slater was sent to? I am beginning to think this is not my man, but is possibly the one from Bolton Lancs.
Mine was known to have been on Jersey July 1869, and prior to early 1869 in Royal Artillery. Although I believe him to have been born in Sussex, this does not seem to allow time for him to have incurred a prior conviction. He joined the RA when he was 17.
Looks like I am back to the drawing board.
Thanks again for your help.
Liza
