As marriage records were often important documents for the couple it is suggested that when a marriage is recorded the information is usually quite accurate. That doesn"t mean that all couples married according the rules of the church or at the appropriate time or place.
As we have seen above, Hardwick"s Act was introduced to tighten up abuses that had been happening. It is always worth checking how the marriage took place, as extra information might be useful.
The banns book might record where either party were living if not of that parish. You will often see the abbreviation "otp" meaning of this parish noted in registers.
If the marriage was by licence, the allegation (a sworn statement by the couple alleging there be no impediment to the marriage) might give indication of age or parents if one of the parties was a minor (under 21).
Remember that until 1929 boys could marry at the age of 14 and girls at 12, provided permission was received from the parents.
Parents are seldom recorded in marriage registers but after 1754 witnesses must be noted and they may be family members and hence useful clues. Usually the marital status and place of residence of the bride and groom will only be noted after 1812.
