The wife of which US President had a maiden name the same as her husband's surname?

Born Anna Eleanor Roosevelt (/ˈɛlᵻnɔːr ˈroʊzəvɛlt/; October 11, 1884 – November 7, 1962) was an American politician, diplomat, and activist. She was the longest-serving First Lady of the United States, having held the post from March 1933 to April 1945 during her husband President Franklin D. Roosevelt's four terms in office, and served as United States Delegate to the United Nations General Assembly from 1945 to 1952. President Harry S. Truman later called her the "First Lady of the World" in tribute to her human rights achievements.

In the summer of 1902, Eleanor encountered her father's fifth cousin, Franklin Delano Roosevelt (1882–1945), on a train to Tivoli, New York. They began a secret correspondence and romance, and became engaged on November 22, 1903. Eleanor married Franklin on March 17, 1905 (St. Patrick's Day), in a wedding officiated by Endicott Peabody, the groom's headmaster at Groton School.
