Hi Brian, In the book ALPHABETICAL INDEX TO THE TOWNLANDS AND TOWNS OF IRELAND I find Ballyvadin, County Tipperary, S.R.; Barony Middlethird; Parish Magorban; Poor Law Union in 1857-Cashel; Ballyvadin, County Tipperary, S.R.; Barony Middlethird; Parish Cloneen, Poor Law Union in 1857-Cashel. I don't have the Ordnance Survey Maps, but the numbers show that they are on sheets 61 and 62. Hope this helps. Linda
