An explanation for the name Elen Luyddog, as luyddog is the adjectival form of the noun lluydd, meaning host. For this reason, her name in English is sometimes given as ‘Helen of the Hosts’. She is also known as St. Helena of Caernarfon, and is sometimes confused with St. Helena of Constantinople, the mother of the Emperor Constantine. There is a Roman road in Wales called Sarn Helen (‘Helen’s Way’), and this is sometimes used to support the claim made in the story that she was involved with building roads (Ffyrdd Elen Luyddog would translate as ‘Elen Luyddog’s Roads’). However, the validity of the name Sarn Helen is itself questionable.
