As with all places in Arkengarthdale, there is no record for the location in the Domesday Book, however, in 1280, it was recorded as Exherlede. The origin of the name is uncertain. The first element in the name seems difficult to trace, but the second element is likely to be Old English or Old Norse hlið 'slope'.
