Cregneash is reckoned to have been the last place in the Isle of Man, where the Manx language -- learnt as a birth-speech -- remained customarily used in daily conversation: this lasting until about the 1940s. Such a status for the Cornish language is considered to have ceased to be, roughly half a century earlier: accounts / theories as to exactly "where and when", vary -- one "contender", is an old couple at Budock Water near Falmouth, who reportedly spoke Cornish with each other as at the 1880s. (Present-day movements to revive the languages, would be felt to be a different thing -- essentially artificial, no matter how admirable.)
