Update - not sure whether they released this by mistake and have now withdrawn it?
The Cheshire Parish Registers are showing up as new on ancestry, but the Card Catalogue currently says number of records - 0, and there is no browse option. So I don't know how many records there are or which parishes are included. The "about" section says images are included, but I haven't managed to find any so far. Also the search results are terrible at the moment, not showing event type, event date, or place, but I think the same was happening to me on a different database earlier, so hopefully it has actually been indexed properly and is just glitching at the moment!
I don't know whether it includes anything which isn't already on Findmypast.

Maybe try it tomorrow?
