Though I've looked at the film before, I also need to look at this film from the LDS: Film or fiche number 1041086

Film/fiche search results Items 1 - 2 Parish registers for Rothesay, 1691-1855 Church of Scotland. Parish Church of Rothesay (Buteshire)

Despite this description, according to the FamilySearch Wiki, it actually contains these records:
Births: 1673-1694

Also according to that website, there are existing Kirk Session records for Rothesay:

Here is a list of the surviving Kirk session records for this parish:

Minutes 1658-1661, 1685-1936 Communion Roll 1835-1841 Note: Available at the National Archives of Scotland, Edinburgh, record CH2/890.

This would require a trip to NAS, though, apparently. Ah, another thing to look at in Scotland!
