I don't understand how to use parish records to trace a single person's lineage before 1800. Parish records of marriage from the 1700s generally do not include parents' names, ages of the couple, or their places of birth.
For example, I am looking for birth records for Elizabeth Parker and James Harris, who married in Limpenhoe, Norfolk, England on May 16, 1802. While they are both of the Limpenhoe Parish at the time of their marriage, Limpenhoe has no parish records of their births. There are multiple people born around the same time and place with the same names, and since I don't have exact birthdates or birth locations for either person, I am not sure how to figure out which is the correct birth record, if any.
Is there something I am missing? Are there complementary records from the 1700s in Norfolk County I can cross-reference?
Thank you so much.
