A Catholic priest in rural 18th century Lancashire used space in the notebook containing baptisms, marriages and deaths for anything else he wanted to write. There are recipes, cures and journal entries such as invitations to supper. It may have been the only notebook he had.
An Irish register has a piece of paper stuck on a page. It seems to be about settlement of a dispute or a debt between 2 parishioners, witnessed and recorded by the priest. Unfortunately the paper obscures most entries on the page.
