incorrect citation

Ah! It's an example of FamilySearch's general mishandling of indexes of multi-part films. Usually they apply the location of the first part to everything indexed on the film; this is the second time I've encountered a later part being (mis-)applied instead. Apparently, the indexing system that fills in the record location field(s) (i.e. placenames that are not typed in by indexers, but supplied by a pre- or post-processing step) assumes that all films or image groups are homogeneous. It's a very widespread error, resulting in events "credited" to the wrong county or state -- or sometimes even country -- in all parts of the world. Over the decade or so that I have been using FamilySearch, I have submitted countless error reports about the results of this flawed process, but nothing has ever changed, and as far as I can tell, it is still in use.

What you can do is edit the citation on Joseph Parker's Sources tab, correcting the title and supplying a correct citation in the Notes/Description field. You can also edit the index entry to correct the marriage place. If you're feeling particularly generous with your time and energy, you can go through and correct the marriage places for everyone indexed on the page, or eventually in the entire book, which might make it easier for other people to find their relatives, but would be a lot of tedious work. It also wouldn't correct the citations or the collection title shown for the index entries; those are not user-editable entities, and there's apparently nobody at FamilySearch tasked with correcting them, either.
