In 1754, seventeen-year-old Georgiana Poyntz met twenty-year-old
John Spencer, who had inherited enormous wealth from his great-grandmother,
Sarah Churchill, Duchess of Marlborough. She considered him "handsomer than an angel," and they felt an instant attraction for each other. She wrote to a friend, "I will own it, and never deny it that I do love Spencer above all men on Earth." Spencer was uncertain if he would have his family's approval for the match and opted to spend several months travelling until his twenty-first birthday, when their approval would no longer be necessary. On his return they recognised their love had persisted, and shortly after his birthday they married in a secret ceremony on 20 December 1755 at
Althorp, the Spencer family seat in
Northamptonshire. The ceremony, held in an upper bedroom, occurred during a ball held in Spencer's honour with five hundred guests in attendance. The marriage was made public five days later, and the couple was presented at court during the following year. Their early years together were happy, and their eldest child,
Georgiana, was born in 1757 at Althorp. Georgiana preferred her firstborn, "Dear little Gee", to her younger children,
George (born 1758) and
Henrietta (born 1761). The Spencers owned many lavish estates, but preferred to reside at Althorp. In 1764, the family moved to their newly built London residence,
Spencer House. Intended to be worthy of Spencer's large collection of antiquities, the lavish residence took seven years and £50,000 to build. A
Whig, in 1756 John entered the
House of Commons as MP for Warwick, and in 1761 was awarded a viscountcy by the leader of the party, the
Duke of Newcastle. Newcastle's party fell into opposition in 1762, and Spencer's loyalty was rewarded with an earldom on the duke's return to power in 1765. The Spencers were generous patrons of writers and artists, and often hosted plays and concerts at Spencer House. According to biographer Donna T. Andrew, Lady Spencer was "exceptionally intelligent and well educated"; she was fluent in French and Italian, possessed some knowledge of Greek, and was "accomplished in botany." Her correspondence with the Hon. Mrs Howe "is reputed to be the largest single private collection of letters in the
British Library." Lady Spencer was known as a philanthropist among her contemporaries, and was a founding member of the Ladies Society, "one of the first philanthropic organisations systematically to investigate the characters and circumstances of those who appealed to them for assistance." She communicated with philanthropists such as
Jonas Hanway and charitable organisations, often advising them on how best to use the resources given to them. ==Widowhood and death==
