River Nar Wikipedia
The River Nar is a river in England, a tributary of the River Great rises at Mileham near Litcham in Norfolk and flows 15 miles west through Castle Acre and Narborough (the latter giving the Nar its name), joining the Ouse at King''s Lynn. It has had a variety of alternative names, such as the Setch, the Sandringham, and Lynn Flu, though these are rarely, if ever, used today.
