A member of a doomed 1845 Arctic voyage has been identified by researchers who matched his DNA with that of a living descendent from South Africa.
Tests confirmed skeletal remains recovered from an island in northern Canada were those of John Gregory.
Gregory was an officer on British explorer Sir John Franklin's ill-fated expedition to chart the Northwest Passage in the Canadian Arctic.
The expedition was a disaster, ending in the deaths of all 129 crew members.
When their two ships - HMS Erebus and HMS Terror - became trapped in the ice, the crew vanished into the frozen Arctic.
