No, not with you at all, sorry.
Can you use an example with fictitious names to make it easy to follow, using (married name), (maiden name) or whatever in brackets

As I mentioned, have you checked the index to see if other surnames have been indexed which don't necessarily show on the baby's BC as the/a surname?
