Birth and baptism
Louise was born prematurely on 8 November 2003 at 23:32 GMT at

Frimley, Surrey, after her mother,
Sophie, who was then Countess of Wessex, was rushed there by ambulance from their home at
Bagshot Park, Surrey. Louise's father,
Prince Edward, then Earl of Wessex, was not present for the birth because it occurred suddenly and while he was on an official visit to Mauritius. Louise was delivered by emergency
Caesarean section due to
placental abruption, which caused severe blood loss to both child and mother. Louise was transferred to a neo-natal unit in
St George's Hospital, Tooting, London, as a precaution. Meanwhile, her mother remained at Frimley Park until she was well enough to be discharged, on 23 November 2003. Her name, Louise Alice Elizabeth Mary, was announced on 27 November.
