largest of several islands WNW of Catharina Point, Robert Island, was roughly charted by Powell, 1821-22, when the name Heywood's Islands (Powell, chart, 1822a) or Heywood's Isles (Powell, 1822b, p.5; Foster and Kendall, chart, 1829a) was applied collectively to the present feature, Cornwall Island and the islands forming Clothier Harbour, after Capt. Peter Heywood, RN (1773-1831), commanding HMS Nereus off the E coast of South America, 1810-13; formerly a midshipman in HMS Bounty (Capt. W. Bligh, RN), 1786-89, who was detained by the mutineers in the ship, then court-martialled and convicted of mutiny on his return to England from Tahiti in 1792, but later pardoned unconditionally.

Rocky, crescent-shaped island lying 1.5 mi WNW of the N tip of Robert Island, in the South Shetland Islands. The name Heywood's Isles, for Capt. Peter Heywood, RN, was given by George Powell in 1821-22 to a group of islands off the NW coast of Robert Island. In 1935, DI personnel on the Discovery II charted these islands, giving the name Hummock Island to the feature here described. Air photos now show that a group name for the islands is not required and the name Heywood Islands has been vacated. The alteration of Hummock Island to Heywood Island retains Powell's original naming in the area and eliminates a duplicate name.

El personal del Discovery II en 1935 la cartografió y le dio este nombre descriptivo. Isla rocosa en forma de media luna de 1 milla de largo, situada a 2,5 millas al NNE de la punta W de isla Robert y a 4 millas al ENE de isla Table, en las islas Shetland del Sur.
