John Adams on his Experiences with British Unitarians

Here. A taste:

During the three years, that I resided in England, I was Somewhat acquainted, with Lindsay, Disnay, Farmer4 Price, Priestley, Kippis, Jebb, Vaughans, Bridgen, Brand Hollis &c &c &c. even Dr Towers was not personally unknown to me, A Belsham was once introduced to me, probably the Author of Lindsays Memoirs. I had much conversation with him. Whether he is a Brother of Belsham the Historian, I know not, Lindsay was a Singular Character, unless Jebb was his parrallel, Unitarianism and Biblical Criticism were the great Characteristicks of them all. All were learned, Scientific, and moral, Lindsay was an heroic Christian5 Philosopher. All, professed Friendship for America, and these were almost all, who pretended to any Such Thing.

Every single one of those names is worth researching.
