Amy Roberta was a prolific Welsh writer who wrote over 90 romantic novels between 1905 and 1972. She also published short stories, an autobiography, and two books of memoir. From 1909 to 1918, her marital name was Mrs Oliver Onions, then she became Amy Oliver once her husband changed his name. Amy Roberta Ruck was born on August 2, 1878, in Murree, Punjab, British India, as the eighth child of Eleanor D'Arcy and Colonel Arthur Ashley Ruck, a British army officer. Ruck attended St Winifred's School in Bangor, Wales, after his family relocated there. In 1909, Ruck married fellow novelist (George) Oliver Onions (1873-1961). They had two boys, Arthur (born 1912) and William (born 1913). Her husband legally changed his name to George Oliver in 1918, but continued to publish as Oliver Onions. Berta and her husband moved to Aberdyfi from London in 1939. Berta Ruck was widowed in 1961. In the 1970s, the BBC interviewed her about her Victorian-era existence. She died in Aberdyfi on August 11, 1978, nine days after her 100th birthday.
Many of Ruck's letters and papers are preserved at the National Library of Wales.
