I havn't sorted the 1676 epis wills that Sue states were definitely in the index she saw - there are no Maughold wills at all in 1676 Epis wills as filmed at museum (Manx Museum film EW21 but I don't know how this corresponds to Mormon numbers) - there would not appear to be any unfilmed 1676 wills (or if there are Wendy was not aware of them and all Epis wills seem to have been neatly bundled prior to the filming in c. 1964 - there being just the one bundle which would seem to correspond with those on film judging from 1st and last pages )
there are no Lib Vas entries at all for Maughold in 1674 (not even a nil return) - I don't think I've missed them as there is a blank in Wm Cubbon's index to parish entries for this year - the only suggestion I have is to look at lib assed around this period and see if the Wm Corkill entry is marked for a change at the next court - There is a 1603-1608 period will in Episcopal for a John Corkill who is possibly father of the Wm
