Encyclopædia Britannica, 11th Edition, Volume 4, Slice 2 states that he was brother of Francis Aungier, 3rd Lord Aungier of Longford and 1st Earl of Longford in Ireland. Though significant research on the life and work of Gerald Aungier is not readily available, his contribution in shaping Bombay is broadly recognised by early prominent historians Da Cunha, Douglas and Edwardes in their separate works. Historian Phirozshah Malabari dedicates a full chapter to Gerald Aungier in his book "Bombay in the Making".
