In 1976, while she was studying to become a barrister, she met future Prime Minister and husband Tony Blair.
She obtained a pupillage in the chambers of Derry Irvine ahead of him, although he was also taken on.
Married on 29 March 1980, the Blairs have three sons and one daughter: Euan (born 1984), Nicholas (born 1985), Kathryn (born 1988), and Leo (born 2000).

Leo was the first child born to the wife of a serving British Prime Minister in over 150 years, since Rollo Russell was born to Lady Frances Elliot-Murray-Kynynmound and Lord John Russell on 11 July 1849.
Another pregnancy at the age of 47 ended in miscarriage in early August 2002.
The Blair children attended Catholic secondary schools, including The London Oratory School.
All four children have Irish passports, by virtue of Tony Blair's mother, Hazel Elizabeth Corscadden, a Protestant, the daughter of George Corscadden, a butcher and Orangeman who moved to Glasgow in 1916 but returned to Ballyshannon in 1923, where Hazel was born to George and Sarah Margaret (née Lipsett), above her family's grocery shop.
Via her father, Blair and her younger sister Lyndsey have six half-sisters, including British journalist Lauren Booth.

Her first grandchild (a girl) was born in October 2016.
