Sorry Bedfordshire boy, I should have made myself clear, I was referring to the practice by Family Search of putting the parishes of Houghton and Witton on the same film as Holywell cum Needingworth and only indexing it as Holywell cum Needingworth!
That is definitely naughty as Houghton and Witton (or Wyton) are very separate parishes from Holywell cum Needingworth and should be indexed as such. It creates the wrong impression that there are two baptisms etc., when there is only one (albeit probably different filming sessions).
This just shows that local knowledge is vital to understanding a register
