What is "wadesmill"

Wadesmill is a hamlet in Hertfordshire, England, located on the north side of the River Rib with an estimated population of 264. Running through the center of Wadesmill is the road formerly known as the A10 - the main London to King's Lynn (via Cambridge) road - but now that the A10 by-pass has been built, Wadesmill and surrounding villages have returned to the quiet of former times. The route that was formerly the A10 is an ancient one with portions of it following the line of the Roman Road Ermine Street. Ermine street also figures as the former main street in Wadesmill's adjacent village Thundridge.
