The Brandsbutt ogham reads IRATADDOARENS
Inchyra =INEHHETESTIETD
One of the ones considered to be translated is the Lunnasting stone Shetland which has Nehton later gaelicised to Nechtan.
Theres one in the museum near me with Nehtetri or Nehtetreb written on it, from Ackergill.
Is the Nehton one a straight translation from ogam just using it as an alphabet? I wish I knew enough about ancient languages to apply the "decoder" of the Berla Egair naSaer to them too.
rataddoarens would appear to be the one on brandsbutt
