LOch NcfSy according to the tradition of the highland bards, 
took its name from one Nyfus an Irip hero, who, together 
with jDornadilla his wife, iettled a colony in Straih-harig-^ the 
promontory, upon which he had his refidence, is to this day 
called '■Jjomi iJearniUy from the name of his wife 3 and becaule 
he was the fiift that ever attempted to fit out boat, or barge, 
upon this lake, it is after him called I.och Nefs:, it is 24 miles in 
length, and in moft places two in breadth 3 one Geo. Scot found-
