Man's Death is Death Of Dialect

BBC:

Bobby Hogg, a 92-year-old resident of the Scottish fishing village of Cromarty, died earlier this week, taking a local dialect along with him. According to the BBC:

The dialect is believed to have arrived in the area with fishing families that moved north from the Firth of Forth in 15th and 16th centuries. The families were thought to be the descendants of Norse and Dutch fishermen.

Hogg and his brother, who died last year, are believed to be the last two people fluent in the language. In 2009, a researcher recorded some of their conversations and created a lexicon of the "Cromarty Fisherfolk Dialect" [PDF]. Hundreds of words and phrases are documented, including this one: "A'm fair sconfished wi hayreen; gie's fur brakwast lashins o am and heggs" – or "I'm so fed up with herring, give me plenty of ham and eggs for breakfast." That phrase survives in print, but it will likely never be spoken again.
It's not so rare for such a cultural deletion to occur. A language goes extinct every 14 days, according to National Geographic's Disappearing Languages project. More than 7,000 languages exist today. By the end of the century, that number could be cut down to less than half.

The radio story on this said there were three dialects in that town, one in use with town folks, one for farmers and one for fishermen.  The fisherfolk dialect was the last surviving.  There were some words my roommate in college and his brother used which maybe were their own dialect. But they will live a while longer, and each have several kids, so that will probably continue.
