When Margaret is searching through the Public Records of Births and Marriages each entry gives full details, is handwritten, and sorted by town and presented in chronological order. In reality, to protect data they are single-line typed entries giving basics and references for obtaining full details, for anywhere in the country, and sorted alphabetically by surname for each quarter of the year.
Although Margaret consults a range of national birth and marriage registers they all appear to have been written in the same distinctive handwriting.
