In 1839 John Williams's missionary work whilst visiting the New Hebrides came to an abrupt end, when he was killed and eaten by cannibals on the island of Erromango whilst he was preaching to them. He was traveling at the time in the Missionary ship Camden commanded by Captain Robert Clark Morgan (1798-1864). A memorial stone was erected on the island of Rarotonga in 1839 and is still there today. His widow is buried with their son, Samuel Tamatoa Williams, at the old Cedar Circle in London's Abney Park Cemetery, the name of her husband and the record of his death described first on the stone. John Williams' remains were sought by a group from Samoa and his bones were brought back to Samoa, where throngs of the LMS mission attended a funeral service attended by Samoan royalty, high-ranking chiefs and the LMS missionaries. His remains were interred at the native LMS church in Apia. A monument stands in his memory across from the Congregational Christian Church of Apia chapel.
