Helen, There are no additional records on Scotland's People to those on IGI. I presume you obtained the mother's name from a subsequent BDM event. You might need to check that. Perhaps have a look at births of other children of Catherine's death. Their ages in census records may give an indication of when parents married. I'm a pensioner and have a thing about paying fees for other people. You were just lucky I had a couple of credits due to expire in a few days. Peter in Sydney
