Helsington Laithes Manor

The original building is believed to date from the 13th Century, when the Manor of Helsington belonged to Margaret de Ros. The West end of the main block is of medieval origin, probably late 15th C. It is said to have a chapel with a pre- Reformation window. Helsington Manor was owned by Marmaduke de Thwenge. At his death in 1323 it passed to his son, William de Thwenge and in 1374 the property, in the estate of Thomas de Thwenge, passed to Robert de Lumley.
The year 1511 brings the first reference to Helsington Laithes which passed to Sir George Lumley.  The House then came into the hands of Henry VIII, who in 1539 leased it to Sir Thomas Seymour, for 21 years from Michaelmas 1540.
