Owen, William (1803), "Lloegyr", A Dictionary of the Welsh Language, Explained in English, vol. II, London: E. Williams, p. 233: "... that part of ancient Britain, which was inhabited by the Belgians, properly speaking; also England, south of the Humber, exclusive of Wales, Cornwall, and Devon; but now it is the popular name for England in general. ..."
Owen, William (1792), "footnote", The heroic elegies and other pieces of Llywarç Hen, London: J. Owen, E. Williams, p. 75: "... The south part of England, bounded by the Severn and the Humber, exclusive of Cornwall, was the ancient Lloegyr but there is reason to conclude that the name was once confined to a still lesser extent of country; or so much of the southern coast as the Belgic Gauls possessed who did not coalesce in the Cymmry, and there was a considerable difference in their dialects. But Lloegyr now implies England in general."
