Lodge was born in Poland Street, London on 13 June 1756, the son of Edmund Lodge, rector of Carshalton, Surrey and his wife, Mary Garrard, daughter of Richard Garrard of Carshalton.
Little is known of his education, but he briefly held a cornet's commission in the army, which he resigned in 1773.
[2] Lodge wrote Illustrations of British History, Biography, and Manners in the Reigns of Henry VIII, Edward VI, Mary, Elizabeth and James I (3 vols., 1791), which consisted of selections from the manuscripts of the Howard, Talbot and Cecil families preserved at the College of Arms.
He contributed the literary matter to Portraits of Illustrious Personages of Great Britain (1814, &c.), an elaborate work of which a popular edition is included in Bohn's Illustrated Library.
His most important work on heraldry was The Genealogy of the Existing British Peerage (1832; enlarged edition, 1859).
