Grover Cleveland and Frances Folsom made history when they wed on June 2, 1886.
Cleveland is the only president in history to be married inside the White House. They were married in the Blue Room, according to the White House Historical Association. Their marriage also made Folsom the youngest first lady to date, as she was only 21 years old when they wed.
Folsom was the daughter of a longtime friend and law partner of Cleveland's named Oscar Folsom. Cleveland knew Folsom from birth and was nearly 30 years older.

After Folsom's father died, Cleveland became the administrator of the family estate and guided the young Folsom by providing educational advice to her, according to the White House website.
Cleveland was the first Democrat elected president after the Civil War. When Cleveland took office for his first term in 1885, he was unmarried. With her mother's permission, Cleveland sent letters to Folsom while she was going to school at Wells College in New York, according to History.com.
In one of his letters, he proposed to Folsom, according to the source. Their engagement was kept under wraps until just before the wedding.
On June 2, 1886, Cleveland and Folsom got married in the White House. Their wedding was a small event, attended by only 28 guests, according to History.com. Rev. William Neal Cleveland, the president's brother, officiated the wedding along with Rev. Bryon Sutherland, according to the source.
Music was provided by the United States Marine Band under the direction of John Philip Sousa.
Prior to Cleveland's marriage to Folsom, his sister, Rose Elizabeth Cleveland, fulfilled the duties of the first lady.
