An interesting note in a parish register

While browsing the parish registers of Newton Flotman in Norfolk there was a set of entries for the period 1759 to 1765 accompanied by a note which reads...

"The preceeding list of christenings and burials is not to be depended upon as exact. There being no register book in the parish at that time: Nor any account kept from the beginning of the year 1759 to the middle of the year 1763. So that the account during that time was afterwards collected from the memories of the inhabitants by the person who entered upon the curacy of this parish in 1763."

I have found various gaps in parish registers but this was the first note to the effect seen with an attempt to piece some of the missing records together by a curate who took record keeping seriously.
