From Samuel Wharton
AL: American Philosophical Society
[Dated merely Thursday night; probably November 9, 1769.3 A note in the third person to inform Franklin that Wharton has just received via Bristol a letter from the latter’s wife, dated Sept. 20, 1769, saying that the Franklin family was well.]
3. The brigantine Concord cleared from Philadelphia for Bristol at the right time to have carried a letter written on Sept. 20, and arrived in early November. Pa. Chron., Sept. 18–25; London Chron., Nov. 9–11, 1769. Nov. 9 was a Thursday, and it seems reasonable that Mrs. Wharton’s letter reached London at the same time as news of the Concord’s arrival.
