Early in 1974, Mountbatten began corresponding with Charles about a potential marriage to Amanda Knatchbull, who was Mountbatten's granddaughter. Charles wrote to Amanda's mother—Lady Brabourne, who was also his godmother—expressing interest in her daughter, to which she replied approvingly, though she suggested that a courtship with the not yet 17-year-old girl was premature. Four years later, Mountbatten arranged for Amanda and himself to accompany Charles on his 1980 tour of India. Both fathers, however, objected; Philip feared that Charles would be eclipsed by his famous uncle (who had served as the last British Viceroy and first Governor-General of India), while Lord Brabourne warned that a joint visit would concentrate media attention on the cousins before they could decide on becoming a couple. However, in August 1979, before Charles would depart alone for India, Mountbatten was killed by the IRA. When Charles returned, he proposed to Amanda, but in addition to her grandfather, she had lost her paternal grandmother and youngest brother Nicholas in the bomb attack and was now reluctant to join the royal family. In June 1980, Charles officially turned down Chevening House, placed at his disposal since 1974, as his future residence. Chevening, a stately home in Kent, was bequeathed, along with an endowment, to the Crown by the last Earl Stanhope, Amanda's childless great-uncle, in the hope that Charles would eventually occupy it. In 1977, a newspaper report mistakenly announced his engagement to Princess Marie-Astrid of Luxembourg.
