Dorothy "Dora" Wordsworth (16 August 1804 – 9 July 1847) was the daughter of poet William Wordsworth (1770–1850) and his wife Mary Hutchinson. Her infancy inspired William Wordsworth to write "Address to My Infant Daughter" in her honour. As an adult, she was further immortalised by him in the 1828 poem "The Triad", along with Edith Southey and Sara Coleridge, daughters of her father's fellow Lake Poets. In 1843, at the age of 39, Dora Wordsworth married Edward Quillinan. While her father initially opposed the marriage, the "temperate but persistent pressure" exerted by Isabella Fenwick, a close family friend, convinced him to relent.
