This damaged slab was found in a garden in Onchan village in 1841 and moved to the church in 1892. It bears on each face a plain incised cross with a plain ring connecting the limbs.


On one face, an inscription runs up and then down the panel to the left of the cross shaft, then up the panel to the right. A few runes are broken off at the beginning, but the inscription has been translated as '...son erected to the memory of his wife Muirgheal...'


A second runic inscription runs up the face to the right of the cross shaft, and has been translated, with some difficulty, as 'I examine (the runes) and interpret (them) correctly'. Additional runes next to this may signify agreement.


The other face also bears runes. Above the head of the cross is the word for 'cross', and, in the opposite direction, 'of Jesus Christ'. At the foot of the face another inscription reads, 'Thorid carved (these) runes.'
