Hi Joe, don't worry too much about the two townlands, that happens all the time in Irish research. If we could back track a little, could you tell us how you got your Coyle/Friel details?
Was it from someone in your family or a cert or census of some kind?
The way to work this out is by means of Mary Coyle's birth or baptism cert, I think,
and as she was born after births had to be registered in Ireland, unless you are very unlucky, there should be a registration. The cert will tell us which parish she was born in, and may give other to help us dig further.
If You do have it already, could you copy the details, church married in, parish, registration district, witnesses etc, as these will all give clues to Roughpark. Any Coyle/Friel info you have could help - did the family leave Ireland?
