John Carteret, 2nd Earl of Granville

Hume had some things in common with Franklin, despite class differences, including an early and fixed determination of a path in life. Here's Hume's: "I laid that plan of life which I have steadily and successfully pursued. I resolved to make a very rigid frugality to supply my deficiency of fortune, to maintain unimpaired my independency, and to regard every object as contemptible except the improvement of my talents in literature."
Thomas Hutchinson, 1711-1780. Governor of Massachusetts, 1771-74. A descendant of Ann Hutchinson, he was a substantial figure in the colonies. It was his (and Andrew Oliver's) correspondence with Thomas Whately, private secretary to the Prime Minister Grenville, which was revealed by Franklin and which did so much to sour the Massachusetts colonists' view of the British government's intentions. He was replaced as Governor by Gen. Gates in 1774 and settled in England. His history of Massachusetts is said to be a very good reference.
George Keith, 1638-1716. Scottish-born Quaker who came to Pennsylvania in 1686. He was a disputatious sort and soon quarreled with the Quaker establishment. For a while he led a schismatic meeting, but eventually returned to England and became an Anglican.

This leads to Bradford's arrest and eventually his move to New York where he advised Franklin.
Sir William Keith, 1680-1749. Son of a Scottish baronial family, he became governor of Pennsylvania, after long negotiation, in 1717.

Hardly ever a victor, he nonetheless retained a military reputation and died as colonel of a foot regiment.
Bernard de Mandeville, 1760-1733, English satirist. His Fable of the Bees, a combined political satire and commentary on contemporary philosophical questions, was occasionally banned and Mandeville was considered a rather wicked man. Here's the gloss of the Fable from Encyclopedia Britannica (1911). Mandeville asserts that
The higher life of man is merely a fiction introduced by philosophers and rulers to simplify government and the relations of society. In fact, virtue (which he defined as " every performance by which man, contrary to the impulse of nature, should endeavour the benefit of others, or the conquest of his own passions, out of a rational ambition of being good ") is actually detrimental to the state in its commercial and intellectual progress, for it is the vices (i.e. the self-regarding actions of men) which alone, by means of inventions and the circulation of capital in connection with luxurious living, stimulate society into action and progress. In the Fable he shows a society possessed of all the virtues " blest with content and honesty," falling into apathy and utterly paralyzed. The absence of self-love (cf. Hobbes) is the death of progress. The so-called higher virtues are mere hypocrisy, and arise from the selfish desire to be superior to the brutes. " The moral virtues are the political offspring which flattery begot upon pride." Similarly he arrives at the great paradox that " private vices are public benefits. . . ." He endeavours to show that all social laws are the crystallized results of selfish aggrandizement and protective alliances among the weak. Denying any form of moral sense or conscience, he regards all the social virtues as evolved from the instinct for self-preservation, the give-and-take arrangements between the partners in a defensive and offensive alliance, and the feelings of pride and vanity artificially fed by politicians, as an antidote to dissension and chaos.

Though opposed to appeasement in 1775, he proposed a peace bill in Parliament in 1780.
Josiah Quincy, 1709-1784. Boston lawyer, father of the Josiah Quincy who took the American grievances to England in 1774 and grandfather of the Josiah Quincy who became president of Harvard University. The Quincy family was one of the richest and most prominent in the Bay Colony.
James Ralph, 1695-1762. A friend of Franklin from the age of about 18, he fancied himself a poet. Ralph went to London with Ben Franklin in 1724 (abandoning a wife and child) and never returned to Philadelphia. He was was enough of a poet to be lampooned by Pope in The Dunciad, and enough of a polemicist to earn a pension when George III came to the throne.

Silence, ye wolves! While Ralph to Cynthia howls,
And makes night hideous;--Answer him, ye owls!
