Elizabeth Somerset, 3rd Baroness Herbert was the sole heir and daughter of William Herbert, 2nd Earl of Pembroke, and his first wife, Mary Woodville. Her father died in 1490, and she inherited extensive lands in Wales. As her father had no sons, she succeeded to his barony, but could not succeed to the earldom, which was restricted to the male line. She was made a ward of King Henry VII of England, and married Charles Somerset on 2 June 1492. Their only son, Henry, was born in around 1496. In 1504, Somerset was created Baron Herbert. Elizabeth died on 27 August 1507, and was buried in St George's Chapel, Windsor Castle. The following month, further estates, including the lease of Caldicot Castle, devolved on Elizabeth's husband on the death of her uncle, Sir Walter Herbert. The addition of Herbert's estate made Somerset the most powerful landowner in South Wales. He had married for a second time by 1511, and was made Earl of Worcester in 1514.
