In Market Rasen in Lincolnshire there is a house called Sheffield Manor which we know is named from the family. In the 14th Century, the Manor of Market Rasen was divided into three and one section came to the Sheffield family. Butterwick and Normanby (which I know were residences) are both about 15-20 miles away so I am guessing it was a member of the family from one of these areas. Sheffield Manor is still in Market Rasen today and I am trying to help the current residents find out a bit about their house. If there is anyone who can give me any more information I would love to hear from you.
