Siân Thomas (born 20th September 1953) is a British actress known for her extensive stage career as well as television and film roles, including Amelia Bones in 'Harry Potter and the Order of the Phoenix', Lady Bareacres in 'Vanity Fair', and a role in 'Perfume: The Story of a Murderer'.
Contrary to this article's earlier claim, research indicates Siân Thomas was born in Stratford-upon-Avon, England, and spent part of her childhood in Canada. Her Welsh connection is genuine but ancestral: she has been described as being of Welsh heritage through her parents, though sources do not specify which parent or which part of Wales the family came from, so no specific place is claimed here.
