Lady Jane Seymour (c.1541-1561) was an influential writer during the sixteenth century in England, along with her sisters, Lady Margaret Seymour and Anne Seymour, Countess of Warwick.[1] She was the daughter of Edward Seymour, 1st Duke of Somerset, who from 1547 was the Lord Protector of England after the death of Henry VIII and during the minority of Jane's first cousin, Edward VI. She was thus the niece of Henry VIII's third wife, Queen Jane Seymour, whom she was probably named after. She was the sole witness to the secret marriage of her brother Edward to Lady Catherine Grey (a potential heir to Elizabeth I) in 1560. She died a year later, aged 20, probably of tuberculosis.
The Seymour sisters tended to work together, with their most famous work being a collection of 103 Latin distichs for the tomb of Margaret de Valois, queen of Navarre and also an authoress, which was published in 1550.
