I think you've got it! It all hangs together. Thank you ciderdrinker and Sinaan, and the geographic context info is interesting as well Kiltaglassan. It's amazing, especially with the time difference. I wrote the query at bedtime and woke up to the answers.
Is it possible get any more information about James Crimeen? Such as burial information or info about his wife and children? It looks very much as if James is a direct ancestor of mine. One thing I'd be particularly interested in is birth or christening info for my ancestor Mary, born c1834, who was presumably his daughter.
Yes, they were Catholic. Would there be a local Catholic church that kept parishioner records, or had a graveyard with headstones?
I am in the process of moving house so cannot properly process everything at the moment. But there is something I am curious about, which is the pronunciation of Crimeen. I realize this is difficult to answer without a voice recording. Would it be anything like Crimean as in the Crimean War?
