Remarriage and family
On 26 December 2001, Rowling married Neil Michael Murray (born 30 June 1971), an anaesthetist, in a private ceremony at her home, Killiechassie House, near Aberfeldy.[113] Their son, David Gordon Rowling Murray, was born on 24 March 2003.[114] Shortly after Rowling began writing Harry Potter and the Half-Blood Prince, she ceased working on the novel to care for David in his early infancy.[115]
Rowling is a friend of Sarah Brown, wife of former prime minister Gordon Brown, whom she met when they collaborated on a charitable project. When Sarah Brown's son Fraser was born in 2003, Rowling was one of the first to visit her in hospital.[116] Rowling's youngest child, daughter Mackenzie Jean Rowling Murray, to whom she dedicated Harry Potter and the Half-Blood Prince, was born on 23 January 2005.[117]
In October 2012, a New Yorker magazine article stated that the Rowling family lived in a seventeenth-century Edinburgh house, concealed at the front by tall conifer hedges. Prior to October 2012, Rowling lived near the author Ian Rankin, who later said she was quiet and introspective, and that she seemed in her element with children.[21][118] As of June 2014, the family resides in Scotland.[119]"
