She has a younger brother, James, born in 2007.

Louise was delivered by emergency Caesarean section due to a placental abruption that caused significant blood loss to both mother and child.

Titles, styles, and honours Titles and styles

Louise is styled as "Lady Louise Mountbatten-Windsor", although at the time of her birth the palace also used the style "Lady Louise Windsor" in some of its announcements. However, when her parents married, Elizabeth II announced via a Buckingham Palace press release that their children would be styled as the children of an earl rather than as prince or princess. In 2020, her mother stated that Louise retained her royal title and style and could choose whether to use it from the age of 18. As of 2026, she has not used it.
