At the time in question though, ie the marriage - Accrington came under Haslingden Registration District.
I am surprised the words 'Hyndburn Register Office or ........' appear on Lancs BMD. It will be confusing for people - I hadn't noticed that before, but just checked my great grandparents who married in an RC Church in Accrington --- and that says Hyndburn Register Office or Registrar attended.
Hence the current area name is being used, even though it wasn't in use then.

"Users' Guide to the Marriage Indexes"
"1. What areas are covered by the indexes?
.............
These records are now held at many separate register offices. .....
The registration districts in Lancashire have changed considerably since 1837 and very few
records are now held at the offices where they they were originally registered."
"2. What information is contained in the indexes?
From the indexes you can find out: ...
c. The Church, Chapel or Registration District where the marriage was solemnised ........"
d. The Register Office in Lancashire which now holds the records. There have been a large
number of boundary changes since the start of registration in 1837 and as a result many
records have been moved around. "
"Please bear in mind that until recently the main purpose of these indexes was to supply
certified copies of entries in registers. They were therefore written to help the registrar
find an entry on information supplied by an applicant for the certificate. Consequently
they do not always provide information in an ideal format for family historians. "
