On 8 November 1864, she married
John Russell, Viscount Amberley, the son of the former prime minister
John Russell, 1st Earl Russell, and his wife
Frances. Their first child,
John Francis Stanley, was born the next year and followed by twins, Rachel Lucretia and her stillborn sister, in 1868. The couple's last child,
Bertrand Arthur William, was born in 1872. Lady Amberley had a sexual relationship with the biologist
Douglas Spalding, her children's tutor, with her husband's consent. Spalding was encouraged to do research in the Amberleys' home,
Cleddon Hall, Monmouthshire, with Lady Amberley as his assistant. He suffered from
tuberculosis and was not fit for marriage. According to their younger son, the Amberleys were concerned for his celibacy and "allowed him to live with her", though Bertrand Russell wrote that he knew of "no evidence that she derived any pleasure from doing so". The exact nature of Lady Amberley's relationship with Spalding afterwards is unknown, as her mother-in-law found out about it and destroyed their journals and most of their correspondence shortly after Lord Amberley's death. == Views ==
