Elidius

This name is best known for being one of the names that the 8th-century Cornish hermit saint Lide (also known as Elid, Elida, Elide, Lyda and Lyde) was known by. He is the namesake of the (now uninhabited) island of St. Helen's in the archipelago of the Isles of Scilly, which is known as Enys Elidius in standard Cornish. The English name of the island is said to be a corruption of the saint's name.

With that said, Elidius is most likely a latinization of the saint's original Cornish name, but even so, it should be noted that there are sources that state that Elidius is derived from the Latin verb elido meaning "to knock out, to strike out" as well as "to tear out, to force out".
