    Overview

The group comprises St. Brigid, Irving, St. Isidore, Chakarov, Hervé, Montojo, Alcheh, Leppe and Bedford Islands. The islands were mapped from air photos by the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and named by the UK Antarctic Place-Names Committee for Sir Joseph Barcroft, a pioneer investigator of the physiological effects of high altitudes and cold.
