Dolly Pentreath was certainly NOT the last native speaker of Cornish. Dolly was bilingual, though some that survived her were monolingual Cornish speakers. As late as the 1890s there was a certain John Davey of Zennor with traditional knowledge of Cornish. The revival began long before Henry Jenner. In the 18th century there was a group of scholars actively working on the Cornish language. Marion Gunn writes that there is .... no shortage of Middle, Late Cornish material... Correct. There is certainly sufficient material in the corpus of Cornish from the 11th to the 19th century to serve as a basis for 20th century Cornish. Regarding the "new words created from Welsh and Breton" mentioned by Donna, when the English find a word for spaghetti, I'll worry about loan words in Cornish. Jon
