Blenheim (1834 ship)

Blenheim was built in 1834 at Jarrow, England. She made three voyages transporting convicts to Australia. She also carried emigrants to New Zealand. She otherwise carried ordinary valuable cargo and in one of such voyages came across what has since been named Blenheim Reef, in the Indian Ocean. She disappeared without a trace, presumed foundered, after August 1846.
