Middleton's first grandchild, Prince George of Cambridge, was born on 22 July 2013 and is third in the line of succession to the British throne. On 2 May 2015, her first granddaughter, Princess Charlotte of Cambridge, was born, who is now fourth in line to succeed to the British throne. Her second grandson, Prince Louis of Cambridge, was born on 23 April 2018 and is fifth in line to succeed to the British throne.
Carole Middleton was born in 31 January 1955 at Perivale Maternity Hospital in Perivale, London, the daughter of Dorothy Harrison and Ronald Goldsmith; she is the older sister of IT recruitment multi-millionaire Gary Goldsmith. She spent her early years in a small house in Southall, attending the local state schools.
She met flight dispatcher Michael Francis Middleton while working with British Airways as a flight attendant. The couple were married on 21 June 1980 at the Church of St James in Dorney, Buckinghamshire. Leeds-born Michael was the son of pilot Captain Peter Middleton, whose mother Olive, was a member of the Lupton family who are described in the City of Leeds archives as being "landed gentry; a political and business dynasty".
In 1986, she and her family returned to West Berkshire, Bradfield Southend, after spending two-and-a-half years in Jordan. Her eldest daughter, Catherine, was aged four and attending the private preparatory college St Andrew's School, Pangbourne. In 1987, Middleton established Party Pieces, a company which began by making party bags and which now sells party supplies and decorations by mail order. By 1995, the firm's directors were both Carole and Michael and was so successful that its headquarters had moved to a range of farm buildings at Ashampstead Common.
The family's wealth is the result of the success of their business combined with the trust funds inherited from Olive Christiana Middleton (née Lupton), whom the BBC reported in 2011 as being Michael Middleton's aristocrat grandmother. This wealth has resulted in the Middletons being reported to be multi-millionaires.
