Rathmore, which page is he mentioned on?
I've never found anywhere to search online for documents that survived the Four Courts bombing, but the LDS' FamilySearch site states that: "Many records were destroyed but not as much as commonly thought. Most probate documents were lost but these losses can be worked around. Only some church records were burned. Many were still with the local church and not at the Four Courts building at the time of the fire." This gives me enough of a glimmer of hope to make an effort to find it, but I don't know where to begin.
About the Civil Ejectments: The Landlord had a choice of proceedures when he wanted to eject a tenant: if he wished to eject for non-payment, the tenant was served with a process stating the amount of rent and costs due; if he wanted to get rid of a tenant who was not in arrears, he had to give six months notice to quit, followed by a process for overholding. Both processes summoned the tenant to appear in court to show why he had not paid his rent, or given up the holding. The difference between them however, was important: the ejectment for non-payment could be stopped by the tenant paying his arrears and costs; the ejectment for overholding could be stopped only if the landlord gave up the case or the tenant got out.

Naturally, I'd like to think that my ancestors weren't kicked out for not paying their rent, but since they're not listed earlier for non-payment or a specific amount due, I'm further led to believe that they weren't in arrears. This would particularly be a kick in the pants for them if they'd previously left Scotland for the same reason, during the Highland Clearances - but I'll have to find some more documents before I can jump to either conclusion.
