Hi there,
May I ask about that m.c. please.... when/where and to whom, what denomination etc .... You mention no parents named... That is definitely of interest to me ... is the section "blank" for both the bride and the groom, does it miss out on those details, is there a line drawn through, or does it comment in any way as to the lack of information. The clergy were required to find out the names of the parents (including nee and any other former names for the mothers), otherwise the marriage could not proceed without a major investigation, and the issuing of a special licence for the marriage to proceed.
Also, the local parish records for the marriage may hold additional information and can usually be accessed by approaching their archivist.
Cheers, JM
