Maria Anne Fitzherbert, 'wife' of King George IV

Maria Anne Fitzherbert (26 July 1756-27 March 1837), née Smythe, married George IV (then the Prince of Wales) in December 1785. The marriage was considered invalid under the Royal Marriages Act 1772 because it had not been approved by the King and the Privy Council. Had permission been asked, it would probably not have been granted, as Mrs. Fitzherbert was a Catholic. Their relationship continued after the Prince's marriage to Princess Caroline of Brunswick, but ended in 1811. Following the death of George in 1830, William IV offered to make her a royal duchess, but she declined.

Her previous husbands were Edward Weld and Thomas Fitzherbert. She had no children.

She is buried in a Catholic church in Kemp Town, Brighton.
