Bradshaw began life in humble circumstances (according to Junius he was a ‘clerk to a contractor for forage’
Despite his experience in Government administration, Bradshaw henceforth regarded himself primarily as Grafton’s confidential man of business for both public and private affairs. He assisted Grafton with the general election of 1768, and came to occupy a key post in Government as Grafton’s link with North. He aided and encouraged Grafton in his wish to be rid of Shelburne; and in the summer of 1768, when Grafton wanted to divorce his duchess, he sent Bradshaw to obtain evidence of her adultery.
When Grafton resigned in January 1770 he obtained for Bradshaw the reversion for two lives of the office of auditor general of the plantations (‘worth upwards of £2500 a year, and which may, and possibly will, be worth double that sum’
You say, my Lord, that you wish me to remain in the Treasury for my own sake, for that of my family, and even for yours. Your bounty has made the two first reasons of no weight ... All your Grace’s friends, as well as mine, know from me that I leave the Treasury because you are no longer at the head of it. I have a high esteem for Lord North, but I cannot transfer that warmth of attachment which is necessary for my situation to whoever sits at that Board ... I wish for no office but under you; and under you there is no employment, however trifling in value, of which I shall not be ambitious, whenever you return to the King’s service.
Bradshaw remained in close touch with Government circles, and acted as Grafton’s agent with Administration. In July 1770 he hinted to North, with Grafton’s approval, that Grafton would like to go to the Admiralty; and he continued to watch over Grafton’s interests in this matter.
William Hickey, who knew the family, wrote of Bradshaw’s ‘gay and social disposition’ and his ‘unbounded extravagance’.
He died 6 Nov. 1774. C. W. Cornwall wrote to Charles Jenkinson on 7 Nov.:
His will,
Bradshaw left his papers to Anthony Chamier: their present location is unknown. A box of papers was to be delivered to the Duke of Grafton: there are letters from Bradshaw to Grafton in the Grafton manuscripts, but none of Bradshaw’s papers.
