Thank you, kind of you to look. I wasn't actually looking to order a cert - I'd managed to discount this marriage by similar means.
I was 'hoping' they were going to give us what we used to have, a searchable index that not only gave the spouse's name but also a date and a venue for the marriage.
Which isn't what has appeared, but for the life of me I can't see the point of a search that gives 3 options, no way to distinguish between them - but you can pay to order a copy.
No point in searching to not at least get a chance of identifying the correct record
