Is there a secondary church attached to it? - sometimes they seem to share a register
I suggested Catholic as a possibility, having transcribed Anglican burials for Formby in Lancashire in the Victorian period. Quite a few were labelled Catholic, as this was before a Catholic chapel had been built and presumably they were interred in local consecrated ground. But the distinction had to be made ...
Well, it's certainly an Anglican parish so not sure. The people I recorded were ones with the relevant surname but not yet sure how (or if) they fit into my tree, so don't have any clues as to their affiliations. Odd that a load of Catholics died in the same week though if that's correct - unless I was looking at 1677 by mistake, rather than 1877!
