If you had family living in Victoria in 1870s, have you thought of looking at the Police Gazettes for information? These are a historian's goldmine of information. Compiled to be distributed amongst the Police Force only, these Gazettes contain details and information that can not be found anywhere else. Far from just listing those who were in the Police Force, or those that were on the 'wrong side' of the law - you will also find entries of missing persons, or they might be a witness to crime, or they may have had something stolen from them, or they may even have found an item, and reported it to the Police.

Of course you also get weekly information on housebreaking, robberies, arson, murders, lost horses and cattle, deserters, escaped prisoners and reports on those released ... as well as some information from interstate police gazettes.
