Certainly ambitious. Unfortunately, with at least one of my ancestors linked to the wrong convict (which blows my mind as I had responded to a call out for info from people with ancestors in this cemetery), I have to take the rest of the two volumes with a grain of salt, which is not what you want when the books cost and arm and a leg, and weigh a tonne! It does give you a path to tread, but always double and triple check sources before taking it at its word. Generally a good rule of thumb with any non-primary sources.
