I found this transcription, while looking for something else in one of my research books. It comes from The Casey Collection Volumes which has some Aghadoe cemetery transcriptions.
I do think this might be related to your family., as you will note that on the Headstone it says Drom. This could be short version of the name of the townland they lived in. (which is same as your Meara family)
I On the headstone it says and I type here just what it says.
