Victoria, Lady Welby, was born Victoria Stuart-Wortley, a daughter of the Hon. Charles Stuart-Wortley-Mackenzie and his wife Lady Emmeline Manners. Following her father's death in 1844, she and her mother travelled widely. Her mother died in Syria in 1855, and Victoria returned to England, where she stayed with her maternal grandfather the Duke of Rutland at Belvoir Castle. She was appointed a maid-of-honour to Queen Victoria. In 1863, she married Sir William Earle Welby-Gregory, 4th Baronet, a Member of Parliament and politician, with whom she had three children and lived at Denton Manor, Lincolnshire. Lady Welby became self-educated by reading, socializing, and corresponding with some of the leading British writers and intellectuals of her era. She wrote her first book, Links and Clues (1881) on Christian theology. Then she started publishing articles in leading English-language academic journals. Her first philosophical book, What Is Meaning? Studies in the Development of Significance, appeared in 1903, following by Significs and Language: The Articulate Form of Our Expressive and Interpretive Resources in 1911. Significs was the name she gave to her theory of meaning. She contributed a long article on the subject to the Encyclopædia Britannica. She put forward her ideas on the reality of time in her book Time As Derivative (1907). She is probably best remembered now for her six-year correspondence with American philosopher Charles Sanders Peirce, which was published in 1977.
