By the early decades of the twentieth century, the archaeological site had come to be known as "Julliberrie's", "The Grave", and "The Giant's Grave" among residents of the local area. The "-berrie" element of the site's name may have derived from the Old English word or , meaning artificial mound or hill. The "Julli-" element might have derived from an individual's name or might be a reference to "jewels", items which locals could have thought were present inside the barrow. In his study of Kentish place names, the etymologist J. K. Wallenberg suggested that the name "Julliberrie's Grave" may have emerged from antiquarian speculation.
