Saint Endelienta was a 5th or 6th-century religious leader from South Wales. As a daughter of King Brychan, she traveled to North Cornwall to assist her siblings in converting the local population to Christianity. She is traditionally associated with the site of Trentinney, where she lived as a hermit. Local legends suggest she was the goddaughter of King Arthur and maintained a simple lifestyle, reportedly subsisting on cow's milk while residing in the Cornish countryside.
