Henry Miller Watts (October 10, 1805 – November 30, 1890) was an American lawyer, politician, and diplomat. Early life Watts was born in Carlisle, Pennsylvania, on October 10, 1805. He was the son of lawyer David Watts (1764–1819), who studied law under William Lewis, and Julia Anna (née Miller) Watts (d. 1869). His older brother, Frederick Watts, was President Ulysses S. Grant's U.S. Commissioner of Agriculture (and the first president of the board of trustees of what is now Penn State University). He was the grandson of Revolutionary War officers Brigadier-general Frederick Watts (who immigrated to Pennsylvania around 1760 from Great Britain) and, his namesake, Lieutenant Colonel, later General, Henry Miller, who led Continental Army units in the siege of Boston and the engagements of Long Island, White Plains, Trenton, Princeton, Brandywine, Germantown and Monmouth.
