it transfers to FamilySearch.org. - The batch numbers on this site belong to the Church of Jesus Christ of Latter-day Saints
a Surname only search – still brings up all entries for BELL.
and has,

I am guessing that when all digital numbers are added – you will be able to view the Parish Register entry - and see it marked illegitimate.
