Georgia O'Keeffe's middle name was Totto, inherited from her mother's family.
She was born Georgia Totto O'Keeffe in Sun Prairie, Wisconsin, in 1887. “Totto” was her maternal grandmother's surname, making her full birth name a useful detail in biographies, museum records, and historical documents about the artist.
The name is occasionally omitted in casual references because she became universally known as Georgia O'Keeffe. It should not be confused with a nickname or an artistic pseudonym: O'Keeffe used her legal name professionally. Her unusual middle name also helps distinguish her from other artists named Georgia in historical catalogs and reference works.
