In 1733, Massachusetts established Bedford as "Narragansett, No. 5" for the benefit of soldiers who fought against the Narragansett people in Rhode Island. The area was also known as "Souhegan East". The settlement was incorporated as "Bedford" in 1750, and was named for John Russell, 4th Duke of Bedford. Lord Russell, a close friend of Governor Benning Wentworth, was the Secretary of State for the Southern Department from 1748 to 1751, and his first wife, Diana Spencer, was cousin to the influential Duke of Marlborough.
