In the early days of the United States, there was no generally accepted title for the wife of the president. Many early first ladies expressed their own preference for how they were addressed, including the use of such titles as Lady. One of the earliest uses of the term "first lady" was applied to Martha Washington in a profile by Mrs. C. H. Sigourney in 1838: Mrs. Sigourney, discussing how Martha Washington had not changed, even after her husband George became president, wrote that "The first lady of the nation still preserved the habits of early life. Indulging in no indolence, she left the pillow at dawn, and after breakfast, retired to her chamber for an hour for the study of the scriptures and devotion".^[7] However, the term "first lady" would not come into common use until the late 1800s.

Harriet Lane, niece of bachelor president James Buchanan, was the first woman to be called first lady while actually serving in that position.

Once Harriet Lane was called first lady, the term was applied retrospectively to her predecessors.

The title first gained nationwide recognition in 1877, when Mary C. Ames wrote an article in the New York City newspaper The Independent describing the inauguration of President Rutherford B. Hayes. She used the term to describe his wife, Lucy Webb Hayes.

Victoria's mother, Alicia Quirino née Syquía, had been killed by occupying Japanese troops towards the end of the Second World War. While President Corazón Aquino (1986–92) was also widowed, the title was not given to her older children who would assist her in official duties.
