The marriage of John Baldwen/Baldwin and Jennet Hartley/Heartley was recorded in two different record books, with minor differences in the information given and the lists of witnesses. Comparing the wording of the two records, and the order of the witnesses, it seems extremely unlikely that either of these records was copied from the other, and both may have been copied from the original marriage certificate. For purposes of comparison, both versions are transcribed here.

 Three men named Roger H[e]artley signed this marriage certificate, and it appears that the designation of junior, which was not present in the Lancaster QM copy, was accidently inserted here by mistake. These three Roger Hartleys were the bride’s father (Roger Sr.), the bride’s brother (Roger Jr.), and the bride’s brother-in-law (husband of her sister Ellen), the marriage taking place at the home of the last of these three. The name Hartley was extremely common in the area.
