William Alexander, known as Lord Stirling, (1726 New York City – 15 January 1783), was an American Brigadier-General during the American Revolutionary War. Alexander was considered male-heir to the title of Earl of Stirling through Scottish lineage (being the senior male descendant of the paternal grandfather of the first Earl of Stirling, who had died in 1640), and sought the title sometime after 1756. His claim was granted by a Scottish Court; however, the House of Lords ultimately over-ruled Scottish law and denied the title, granting Alexander instead the compromise title of Lord.
Lord Stirling commanded the 1st Maryland Regiment that fought at the Battle of Long Island. He lost the battle and was captured but his actions allowed General George Washington's troops to escape. Stirling was returned by prisoner exchange, promoted for his actions, and served with distinction throughout the war. He was trusted by Washington and in 1780 he exposed the Conway Cabal.William Alexander, Lord Stirling in Wikipedia
