Kilcolman (Offaly)

I believe I've traced my ancestry to Kilcolman parish - I've got a DNA link to a descendant from a family line that stayed in Ireland. I found some film online for the parish register:  https://familysearch.org/search/catalog/223772?availability=Family%20His...

Is this the best film available for these records and has this been indexed anywhere?  I've gone through the first 13 or so years, but sometimes the years are a bit fuzzy because there are numerous places where the pages are obviously out of order (not sure where they might be non-obviously out of order).  Wondering if the ordering problem happened with the film, or if it's a problem with the book itself.  Also, some of the images have really poor lighting making most of the records in these images illegible.

BTW, the family line I'm looking at is Marshall - a John Marshall that emigrated to New Jersey around the time of the Great Famine.  If I've got the right record, his parents were John & Sarah Carry.  I also have a cousin I met on ancestry whose ancestor is James Marshall, son of Michael & Bridget Magher (also emigrated to New Jersey about the same time).  If anyone is researching the same family, or is also a descendant, feel free to drop me a line!
