Hello - here's my small contribution. So long ago that I've forgotten which play it was (sorry!) I read one by either Wilde or Shaw, c. 1880-1900, with a character called Jennifer. An englishman queried it because it was completely foreign to him, and she explained that it was the cornish form of the welsh Guinevere. That does make philological sense. In the same period Jenny was the conventional pet form of Jane in England and the USA. I don't know of any link with Ginevra, but that was the given name of Indiana author Gene Stratton Porter and was actually dutch: no celtic associations there. Here in Victoria I have a collateral from Cornwall called Ketura or Kitura, apparently known here as Catherine by extension from the pet form Kitty - one day I must find out how many registrars and clerks were cornish as opposed to english, because that would have an important influence on how they recorded names - so I went to the book that every geneaolgist needs: Bancroft's *Concise Bible Dictionary*, by James P. Boyd (USA: Ottenheimer, 1958). Keturah was one of Abraham's wives; Boyd gives book, chapter and verse and a guide to pronunciation. He's equally useful for Tryphena. The key facts about names in Cornwall are that it is not part of England and the language is not germanic but celtic; that post 1737 it was a country of Dissenters, who chose names from the Old Testament in preference to anything remotely associated with Rome; and that literacy wasn't widespread till well after 1873. If you want the correct spelling of an OT name you'll find it in the King James Bible, where it was fixed in 1611 - so many clerics were so close to illiterate between, say, 1611-1800 that you can't bet that the vicar got it right either, but using the correct spelling as a starting point does help with chasing variants. And for no apparent reason except the spread of english, Cornwall did take up the long-established english habit of putting an N in front of a word beginning in a vowel, e.g. Nuncle (as in King Lear), Nell (Ellen), Noll (Oliver) and Nan, Nanny in Cornwall and Nancy in England (Ann). And another thing... names that in England were fashionable in the C17 such as Francis, Melinda, Clarinda etc persisted in Cornwall well into the C19. If anyone knows why, please share it. Phoebe
