yes the 'gap' years between 1849 amd 1877 are in printed form done by the Priest at St Mary's but are not on IGI - need personal research either in Manx Museum or in IoM Fam Hist library in Peel.
If you are a member the librarian might well be willing to do a look up for you - address etc in your Journal. - For membership see website listed at bottom of Bulletin board
