Jonathan Couch remains. The "History of Polperro", (1871), issued after his death by his son, T. Q. Couch, is his chief work in this department. The stories in this book were re-used by Louisa Sarah Ann Parr in her successful novel about smuggling titled "Adam and Eve". Couch left three sons by his second wife: Richard Quiller, Thomas Quiller (father of Sir Arthur Quiller-Couch), and John Quiller, who all became surgeons (Quiller being their mother's maiden name and Quiller's House the family residence). Thomas practised successfully at Bodmin, and died on 23 October 1884, aged 58. He was a constant contributor to
Bevil Quiller-Couch the Somme and in August of that year he was promoted to acting Major. In September 1917, he was wounded during the Third Battle of Ypres. He was later involved at Cambrai, and by January 1918 went on leave back to England. Towards the end of the war, Quiller-Couch led his battery into action at Noyelles. He last saw action in November 1918 before joining the reserve forces at Villers Pol. Quiller-Couch survived the war without injury only to die at Langerwehe, near Düren in Germany, on 6 February 1919 during the Spanish flu pandemic. He was buried at Cologne,
