Frances Clara Folsom Cleveland Preston (July 21, 1864 – October 29, 1947) was married to the President of the United States Grover Cleveland and was the First Lady of the United States from 1886 to 1889 and again from 1893 to 1897. Becoming First Lady at age 21, she remains the youngest wife of a sitting president.

Frances Clara Folsom was born in Buffalo, New York to Emma Harmon and her husband Oscar Folsom, a lawyer who was a descendant of the earliest European settlers of Exeter, New Hampshire[1].

All of Frances Cleveland's ancestors were from England and settled in what would become Massachusetts, Rhode Island and New Hampshire, eventually migrating to western New York.[2] She was their only child to survive infancy (a sister, Nellie Augusta, died before her first birthday). She originally had the first name Frank (named for an uncle), but later decided to adopt the feminine variant Frances.[3] A longtime close friend of Oscar Folsom, Grover Cleveland, met his future wife shortly after she was born and he was 27 years old. He took an avuncular interest in her, buying her a baby carriage and otherwise doting on her as she grew up. When her father died in a carriage accident on July 23, 1875 without having written a will, the court appointed Cleveland administrator of his estate.[2] This brought Cleveland into still more contact with Frances, then age 11.

She attended Central High School in Buffalo and Medina High School in Medina, New York then Wells College in Aurora, New York. While she was in college, Cleveland's feelings for her took a romantic turn. He proposed by letter in August 1885, soon after her graduation, but they didn't announce their engagement until five days before their wedding.

In honor of Frances Cleveland, Cleveland Hall was constructed in 1911 on the Wells College campus. Originally a library, the building currently holds foreign language classes, as well as classes in women's studies, and a food pantry.[4]
