'''Anne Isabella Noel Byron, 11th Baroness Wentworth and Baroness Byron''' ({{nee|'''Milbanke'''}}; 17 May 1792 – 16 May 1860), nicknamed '''Annabella''' and commonly known as '''Lady Byron''', was an educational reformer and philanthropist who established [[Ealing Grove School|the first industrial school in England]], and was an active [[Abolitionism|abolitionist]]. She married the poet George Gordon Byron, more commonly known as [[Lord Byron]], and separated from him after less than a year, keeping their daughter [[Ada Lovelace]] in her custody despite laws at the time giving fathers sole custody of children.<ref>{{Cite book |last=Markus |first=Julia |title=Lady Byron and her Daughters |publisher=[[W.

Lady Byron's reminiscences, published after her death by [[Harriet Beecher Stowe]], revealed her fears about alleged incest between Lord Byron and his half-sister. The scandal about Lady Byron's suspicions accelerated Byron's intentions to leave England and return to the Mediterranean where he had lived in 1810.

Their daughter, Ada, worked as a mathematician with [[Charles Babbage]], the pioneer of computer science, and is known as the first programmer.
