Very many thanks for checking the marriage, Frances. You came to the same conclusion about Edward Corkill parish clerk as Carol did, who also checked the marriage yesterday - so I saw both your messages when I turned on the computer this morning.
I only have the index to Maughold marriage contracts up until 1800 but very little hope of one for Elinor, even if her mother was from the well-off Ballaterson family, having at least seven elder siblings. (Not on your CD.)
