Surname or Lastname
English
English : habitational name from a place in Cumbria (Westmorland). The place name is recorded in Domesday Book as Lupetun, and probably derives from an Old English personal name Hluppa (of uncertain origin) + Old English tūn ‘enclosure’, ‘settlement’.The name was brought to America by John Lupton, who sailed from Gravesend, England, on the Primrose in 1635, and is recorded in VA three years later. On 24 October 1635 Davie Lupton set off on the Constance bound for VA, but there is no record of his arrival in the New World. A Christopher Lupton is recorded in Suffolk Co., Long Island, NY, c.1635, and a large number of Luptons in NC descend from him. An American family of the name settled in the area of Winchester, VA, in the mid18th century; they can be traced back to Martin Lupton, who was married in 1630 in the parish of Rothwell, Yorkshire, England.
