“ Jeffreys now commenced practice in Westminster Hall, and, seeing little prospect of further advancement from the popular party, to which he had hitherto belonged, began to cultivate fashionable society. With the aid of Chiffinch, page of the backstairs, Jeffreys obtained an introduction to the court, and in September 1677 was appointed solicitor-general to the Duke of York, receiving the honour of knighthood on the 14th of the same month. In January 1678 he was called to the bench of the Inner Temple, and on 22 Oct. was elected recorder of the city in the place of Sir William Dolben [q. v.] ”
