Caithness is the northernmost county on the mainland of
the United Kingdom, and its name records its history.
"Caith" comes from "Catti", later the Clan
Keith, mentioned in
Castles and Families of the North.
comes from the Norse "Nes" meaning a point of land and
so combines the Celt with the Norse as do the people of our
