Tuthill

English: topographic name for someone who lived by a hill used as a lookout station, from an unattested Old English tōt hyll ‘lookout hill’, or a habitational name from some place named with this word, for example Tootle Heights in Lancashire, Tothill in Lincolnshire, or Tuttle Hill in Warwickshire. This surname became established in Ireland in the 17th century, and is now more common in Ireland than England.
