1. Joshua Johnson (1742–1802), born in Calvert co., Md., brother of Gov. Thomas Johnson of Maryland, was employed in London as factor of an Annapolis shipping firm until the Revolution. He then crossed to France en route to America, but having several small children he was discouraged by the prospect of a long sea voyage and settled as a merchant at Nantes, where he undertook various commissions for both Congress and the State of Maryland. JA and JQA visited the Johnsons in Nantes before returning to America in 1779. Johnson returned to London after the war and served as first U.S. consul there, 1790–1797. While on diplomatic service in London, JQA courted Johnson's daughter Louisa Catherine (1775–1852), and was married to her in 1797. See JA, Autobiography, under the present date
