I'm hoping that someone may be able to read the first word of this heading - it's from the baptism records for St John the Evangelist in Baildon in 1798 - one of four versions currently on Ancestry, two of them being typed transcriptions and the other doesn't include the headings or the first column entries.
I do have the transcription issued by Wharfedale Family History Group, and this indicates that the first column shows the place within the family of the person being baptised - i.e. William, son of Joseph Heaton is the 5th child in the family and Sarah is the 5th child of John Bradley.

WFHG show the same sort of information right up until the end 1812.
My reason for asking this question is that I have Aaron Crabtree, baptised in 1798 and the figure in the first column is 10, but if that is so then there are a number of children not being baptised!!!!
Any help gratefully accepted.
