Georgia O'Keeffe’s maiden surname was O'Keeffe, the same surname she used after marrying Alfred Stieglitz.
She was born Georgia Totto O'Keeffe in Sun Prairie, Wisconsin. Her father, Francis Calyxtus O'Keeffe, was of Irish descent, and the family surname was O'Keeffe. In 1924, she married Alfred Stieglitz but did not replace O'Keeffe with Stieglitz in her professional identity.
This makes the name unusual in straightforward biographical questions: O'Keeffe was both her birth surname and her best-known artistic surname. “Totto” was her middle name, not her maiden surname. Stieglitz was her husband’s surname, while Kuhne was the surname of her mother’s family.
Her continued use of O'Keeffe also reflects her independent public career. Although Stieglitz promoted and photographed her, she exhibited and published as Georgia O'Keeffe, a name that became closely associated with American modernism.
