The words under Denomination are place names--Teernevin, Fawnen, etc. They appear next to another column headed Townlands. Sometimes the townland and the denomination are the same but usually they're not. In the broadest sense, denomination means name or category. As I said earlier, since there are more denominations than townlands listed, I'm guessing the denominations were subunits within the townlands. By the time of Griffith's most of the denominations were listed as townlands. Diane
