Too bad it doesn’t actually state English; can you link a reference?
Still sounds Irish to me.
We have others stating Cornish (never heard of that, so must be very isolated) based on a movie.
Cornish is a Celtic language from England, one which has fallen out of use. It is from the Brythonic group of languages, close to Welsh.
As the English/Germans (Anglo Saxons) pushed the earlier Celtic people like Welsh and Scots further West, the Cornish speakers were the ones furthest South, in what is now called Cornwall.
