He matriculated at The Queen's College, Oxford on 5 July 1716, aged 17 and was awarded MA on 15 March 1721.
[1] In 1736 he was appointed Verderer of Windsor Forest, retaining the post for the rest of his life.
[2] Powney was returned as Tory Member of Parliament for Berkshire at a by-election on 5 December 1739.
His son, Peniston Portlock Powney, told the younger Pitt that he considered himself to have lost 20,000 pounds by his father’s connection with the Prince owing among other things to a large loan incurred during the Prince’s residence at Cliveden, which was undischarged on Frederick’s death.
