OK, it's not difficult, BUT I'm confused

The burial entry I found on FindMyPast for John Hood purports to be at St Mary, Selby (as per the transcription) BUT the image is from the Bishop's Transcripts of Burials AND therefore cannot (I think) relate to a Catholic Church

The paperwork is the standard post-1813 paperwork, again I'm not sure what paperwork Catholic churches used. Plus the fact that there is a marriage by licence in 1819 (Bond and Allegation don't appear to have survived). The headings for Baptisms, Marriages and Burials just states the parish of Selby, as do the pages pre-1813.
How wonderful is Genuki

"The church, a peculiar of the Selby Court, is a vicarage, dedicated to St Mary and St Germain, in the deanery of the Ainsty."
The Bishop's Transcripts for 1798 are signed by the Vicar - Thomas Mounsey.
Genuki has a transcribed list of the Abbots and Vicars
in Selby Abbey - 1797 - 1819 - Thomas Mounsey.
Added: 1834 Pigots Directory - "The church, formerly conventual, and belonging to the Abbey, dedicated to St Mary and St Germain ...." Other directories refer to it as just St Germain.
