I’ve two interprations of the inscription “MAQ CERAN AVI ATHECETAIMIN” from http://www.megalithicireland.com/ and “Mac Uí Riaghan” from http://www.attymass.ie/ogham_stone.htm. Both sites have more info.
A very friendly farmer gave me access to the stone
Legend has it that there was a battle at a place known as Pairc na Fola (Park of Blood). There at a low cairn called Cnoc na Fola (Hill of Blood) the slain were buried. At the edge of the cairn is a three stone row containing two ogham stones.
