It was positioned by the South Georgia Survey in the period 1951–57. The rock was named by the UK Antarctic Place-Names Committee for Frank Cabrial, steward on the American brig Frances Alan of New London, Connecticut, who was drowned on October 14, 1820; there is a grave marked by a wooden cross recording this in Ocean Harbor.
