My researcher friend checked the source for these listings from the IGI. Here is her report. "I pulled the info from each of the sheets on the ordinance index for the 4 citations you referred to. Unfortunately, there is no additional info on any of the original papers; statement reads "Record submitted by LDS Church member. NO additional information is available on film (official temple record). Ancestral File may list the same family with the submitter's name and address." However, I didn't find these on the Ancestral File."
As you can see we had no luck. Possibly someone with access to the parish records may find something. Sorry.
