the 'missing' marown marriages can be found in Bishop's transcripts - the actual Parish register is not extant - the Manx Museum filmed some of the BT's but not all (I would be surprised if they are on lds film - however Janet Narasiman transcribed some (not all as certain BT's only surfaced in last couple of years) and possibly it is these ? - all known marriages are on Manxnotebook as are two years of the missing Malew marriages
My complaint is that the parish reg extractions were replaced by 'patron submitted' - in generally these have a 50% error rate (eg wrong year,month etc - I've seen upto 100 years out - supposed partner that is not present in the register (often a guess) - incorrect readings (the stupidities of replacing cannell by connell are easily spotted but there are many more)
