Anna Milbanke

Annabella Milbanke (11th Baroness Wenthworth) married the notorious Lord Byron on 2 Jan 1815, after refusing his first proposal of marriage in 1812. Byron called her his princess of parallelograms, since she was interested in mathematics. She tried to reform him, but her efforts were in vain. Byron treated her badly and amost certainly had an incestuous affair with his half sister Augusta (possibly he was the father of one of Augusta's children). With the help of her parents Annabella obtained a divorce in 1816. By that time their daughter Ada Augusta was just a few months old.
