The suburb of Leonay is situated on the western banks of the Nepean River to the south of Emu Plains and takes its name from the riverside property of the well-known Australian wine grower Hermann Paul Leopold Buring – better known as Leo Buring – and his wife Ida –nicknamed Nay. They built a house on this 376 acre property in 1920 and combined their names to call it Leonay. Although the area was known locally as Leonay it wasn’t officially gazetted as such by the NSW Geographical Names Board until around 1974 after a poll of residents in 1973.
