Hi Martin,
What kind of information were you hoping for? Usually marriages of this date don't give much detail, other than what you found on the IGI. You would need to look at the actual parish record to see if there was anything else. Sometimes the church had a record for banns & if they survived they might reveal something. If it was by licence, the allegation might have more details.
PS. Irret, the marriage was in 1715, so there is no certificate, only the entry in the parish records. Civil registration came into being on July 1 1837, so anything from that date to the present can be ordered.
PPS. Are you refering to an LDS film? In which case, that would be another way of viewing the record.
