Her father died on 16 July 1491, and she inherited extensive lands in Wales.
She was made a ward of King Henry VII of England, and married Charles Somerset, 1st Earl of Worcester on 2 June 1492.
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.
