TRELAWNY (Cornish Gaelic):   Please note that there is no such thing as Cornish Gaelic!!! (My goodness, you're lucky that I spotted this before Phillippa...)

Cornish is a Brythonic, not Goidelic, language,and is closely related to Welsh and Breton; it is related to Gaelic in roughly the same degree as English is related to Dutch. The Cornish text in the DT is uncredited, but it is a 20th century translation into that language from the original English, and was made by "Talek" (real name Ernest George Retallack Hooper), 3rd. Grand Bard of the Cornish Gorsedd (1959-1965). Although he based it in part upon earlier (but also 20th century) translations, it would presumably still be in copyright.

The English and Cornish texts in the DT were both copied from Peter Kennedy's Folksongs of Britain and Ireland (1975).
