I want to know the answer to the following question:
When did Lieutenant-Governor of New South Wales Francis Grose start suggesting Norfolk Island be closed as a penal settlement?
All the background I'm provided with is that "A small party remained to slaughter stock and destroy all buildings, so that there would be no inducement for anyone, especially from other European powers, to visit and lay claim to the place.". Is that enough to answer the question?
Answer: no
