Aghowle(Aghold) Church

[Cambron]

I understand that within the walls of the ancient but now ruined Aghowle Church there was an area reserved for burials of the Nickson family of the 17th and 18th centuries.
Can anyone advise me if there is a memorial or gravestones there and are there any transcriptions available?
I have the transcriptions of the later Aghold St Michaels Church Register 1720 onwards, microfilmed by IGI, although there are significant gaps.
