John Collier by his first wife Marian, née Huxley. Collier married two of Huxley's daughters and was "on terms of intimate friendship" with his son, the writer Leonard Huxley. Collier's first wife, in 1879, was Marian (Mady) Huxley. She was a painter who studied, like her husband, at the Slade and exhibited at the Royal Academy and elsewhere. After the birth of their only child, a daughter, she suffered severe post-natal depression and was taken to Paris for treatment where, however, she contracted pneumonia and died in 1887. Collier's daughter by his first marriage, Joyce, was a portrait miniaturist, and a member of the Royal Society of Miniature Painters. In 1889 Collier married Mady's younger sister Ethel Huxley. Until the Deceased Wife's Sister's Marriage Act 1907 such a marriage was not possible in England, so the ceremony took place in Norway. By his second wife he had a daughter and a son, Sir Laurence Collier, who was the British Ambassador to Norway 1941–51. (https://en.wikipedia.org/wiki/John_Collier_(painter))
