Is there a U.S. president who last or first name starts with 'S'?

Answer 1

Stephen Grover Cleveland, known to us as Grover Cleveland, 22nd and 24th President of United States, is the only U.S. President with a first or last name starting with the letter 'S'. He was named Stephen Grover in honor of a local pastor, but he did not use the name Stephen as an adult. Two U.S. Presidents had middle names starting with 'S', although in both cases 'S' was the name! * President Ulysses S. Grant's birth name was Hiram Ulysses Grant, so although later--by mistake, it turns out--he was known as Ulysses S. Grant, the 'S' stood for nothing. * President Harry S. Truman is actually Harry S Truman, because has parents gave him the middle name "S" in honor of two grandfathers with different 'S' names. Nevertheless, when Harry Truman signed his name, he generally did use a period after the middle-name "S".

Answer 2

As of 2013, not yet, though Presidents Grant and Truman had S for a middle initial.
