Baron Jacobus von Washington (26 January 1778 – 5 April 1848) was a lieutenant general in the Bavarian Army and a distant relative of US President George Washington. Born in The Hague, Netherlands, he was christened James Washington. Most of his adult life was shaped by his participation in wars for and against Napoleonic France and his service to Ludwig I of Bavaria.
The known history of the Washington family goes back to the 12th century. Sir Robert Washington (d. 1324) was the progenitor of the branch of the family residing in Sulgrave Manor, England. One of his descendants, John Washington, emigrated to Virginia in 1656 and was the great-grandfather of George Washington. The brother of Sir Robert, Sir John Washington (died 1331), founded the Hallhead Hall/Adwick-le-street branch of the Washingtons. His descendant, James Washington, accompanied John Washington to Virginia, but returned to England, then shortly thereafter emigrated to Rotterdam, the Netherlands.
