Thanks Annette - everyone's so helpful here!
I know this was a thread for handwriting recognition, and as such I may need to delete this post and move it, but does anyone have any opinion on the consistency, or lack thereof, of the records I've found thus far? There's two little Excel extracts below with what I've got, and I don't want to start going back further on the Pollock line before I can pin this down as best I can.
Again, if I should have posted this elsewhere, apologies, but I thought I ought to continue the conversation here.
Edit: OCD on the Excel column widths!
