Attested: RC Morionio
Where: Glastonbury, Somerset, whose Tor at ST51223862 sticks up from what used to be almost an island surrounded by marshes.
Name origin: PIE *mori- in ancient place names generally referred to marshes and other forms of inland water rather than to the wider sea like Welsh môr. The ending –onium was a fairly general way of forming nouns in Latin.
Notes: The Tor and a chalybeate spring formed the core of an early Christian monastery at Glastonbury.
