there is not a 1:1 mapping between burials and wills - I can see no Wm Garrett will that would probably be in 2nd book at earliest for 1745 + prob in a 1746 (or later) book - I don't think it was missed from the index as Archideaconal wills are numbered and I've looked thro the film of Episcopal wills for that period - however the ordering on the film is somewhat disorganised especially around this period with several wills out out place which may meen that some have been lost
