|Administrative History||Sir Norton Robinson was born post 1713, son of Rear Admiral Sir Tancred Robinson, third baronet, and Mary Norton. His father died in 1754 and Sir Norton succeeded to the baronetcy as fifth baronet on the death of his older brother William on 4 March 1770, inheriting the estates in North Yorkshire. Sir Norton was declared lunatic on 2 May 1770, a Commission and Inquisition of Lunacy into his state of mind and property having been appointed in Chancery on 9 April 1770. In 1775 an Inquiry was launched by order of the Lord Chancellor to consider the proper allowance for the lunatic, with regard to his circumstances and estate.|
With the death of Sir Norton Robinson in 1792, this line of the family failed and he was was succeeded by his first cousin once removed, Thomas Robinson, 3rd Baron Grantham, who became the sixth Baronet.
