During my researches I have found several instances at a variety of parishes where church wardens etc. seem to have acted almost as "professional witnesses" their names appearing several times per page in the registers.
I wonder if that is suggesting the bride and/or the groom were regulars and those 'professional witnesses' were simply there as the 'credible' witnesses that Stan has mentioned.
I have noticed many apparent anomalies between the civil registration records and the parish registers.
In my instances these discrepencies are in New South Wales, Australia, and the differences are between the NSW BDM holdings for marriages and the actual Church registers upon which NSW BDM based their 19thCentury holdings. NSW BDM was formally established in the 1850s, however it took well into the 1880s for the various denominations to provide summary reports on marriages celebrated by their clergys.
It took until 1895 for the disputes (Church v State) to resolve many many issues. Consequently there are many blanks on NSW BDM issued marriage certs for the years 1856 - 1895. For example, the names of the parents of the bride and the groom are often NOT recorded on the civil registrations. These are of course found on the parish registers. Another example is the ages of the bride and the groom are often missing from those civil registrations, and the ages are, of course, usually found on the parish registers.
BUT sometimes even the NSW parish registers do NOT include those details. This is usually for marriages PRE the NSW BDM civil registration era commenced. HOWEVER, sometimes even after the civil registration era commenced, the parish registers for some of the clergy seem to indicate "marriage shops" and very limited details are obtained from those registers. It is not limited to any particular denomination, rather it is limited (at least from my research) to the manners and practices of particular clergymen, and their own understanding of what minimal information they could provide to the secular authorities.
I understand that other British Colonies (both in Australia and elsewhere) have similar difficulties with some of their 19thC marriage records.
