Claire Alexandra Windsor, Countess of Ulster (born Claire Alexandra Booth on 29 December 1977) is the wife of Alexander Windsor, Earl of Ulster, the son and heir of Prince Richard, Duke of Gloucester, and Birgitte, Duchess of Gloucester. She was born at Sheffield, Yorkshire, and went to King's College London to study medicine, graduating in 2001 as Bachelor of Medicine, Bachelor of Surgery (MB BS). She subsequently graduated from University College London as MSc in 2007 and PhD in 2012.[1]

Dr Booth is the elder child of Robert Booth, FCMI, of Weston Turville, Buckinghamshire (born 1948 at Rotherham and a scion of the ancient Cheshire Booth family) by his wife Barbara Patricia, daughter of Wilfred Robert Hitchin.[2] Her younger sister, Joanne Booth, was born in 1979.

Lord Ulster married her on 22 June 2002 at the Queen's Chapel, St James's Palace, upon which her title became Countess of Ulster or Lady Ulster (as appropriate). However, being a physician by profession, she prefers to remain known as Dr Claire Booth. Lady Ulster qualified as a paediatric specialist registrar, after which she became a Consultant Paediatrician with the General Medical Council.[3] On 1 September 2012, she was appointed Clinical Training Fellow (Walport Lecturer) at UCL.


Lady Windsor had her first child, a son, Xan Richard Anders, Lord Culloden, on 12 March 2007, and a second child, a daughter, Cosima Rose Alexandra, on 20 May 2010.[4] Her children are accorded courtesy styles of "Lord" and "Lady", while Xan would become Earl of Ulster were his father to succeed to the dukedom of Gloucester.
