Any access to these Ahoghill records (which seem to start from around 1811) may be very helpful! Alas, I'm not finding anything online, only the PRONI Ref. numbers for Church of Ireland records which are MIC583/9; CR/1/90.
Does anybody know if these are available via rootsireland.ie? If they were, I could take out a short-term subscription but I've been stung by that in the past!
