Which last name is shared by multiple presidents that are not related?

• Johnson:Five surnames have been shared by U.S. presidents, and four of these pairs have been related. Adams and Bush are the names of the two father-son pairs (the Adams pair also share their first name; the Bush pair share a first and a middle name), while William Henry Harrison was the grandfather of Benjamin Harrison. Theodore Roosevelt and Franklin D. Roosevelt were fifth cousins, however FDR's marriage to Theodore's niece, Eleanor, also made him a nephew-in law. The only presidents to share a last name and not be related are Andrew Johnson and Lyndon B. Johnson.
