Having only used the films at Manx Museum are the refs you want those of the old Mormon films eg the will of Elizabeth DeLaPrime in 1799 Malew Archideaconal court #26 is on film 0106233 - Brian Lawson included this in his index - the films at the Museum are catalogued with different numbers and some Museum films appear to be spliced somewhat differently - the Episcopal wills are not numbered (the numbers on the Archidiaconal wills are probably contemporary with the filing of the will) but an index giving frame number on the films was put together some years ago - the early Episcopal wills from 1600 to abt 1700 are poorly indexed but J M Oates has done a very thorough job on indexing these -
