Andrew Wilkinson succeeded his father as estate agent to the Duke of Newcastle and manager for the boroughs of Aldborough and Boroughbridge, and was Newcastle’s dependant in Parliament as well as in Yorkshire. In October 1756, when a by-election was impending at Boroughbridge, he inquired ‘to know your Grace’s pleasure whether I shall continue here till that is over, or be in town at the meeting of the Parliament?’ That he still continued as the Duke’s estate agent in Yorkshire is shown, for example, by Newcastle’s letter to him, 19 Oct. 1753, asking for ‘a complete rental of the estate in your collection’.
Wilkinson’s name does not at first appear in Newcastle’s lists for the general election of 1768. But on 7 Feb., James West informed him that Wilkinson was ‘very desirous of being in Parliament for Boroughbridge if His Grace would permit it’; and Newcastle felt that if his ‘old friend Andrew Wilkinson desires to come into Parliament, and, I suppose, risk his place, (for that must be the condition)’ he could not refuse.
He died 29 Mar. 1784.
