There is a possibility that we are looking in the wrong county, it seems likely that the county border with Co Armagh has split apart a townland with part of it in Co Armagh and part Co Down There is perhaps a religous reason for changing churchand denominationand once done there might be more ie in Scotland?
cant help further
GOOD LUCK ONWARDS
