Isabella Mary were the first names of which famous woman?

Isabella Mary Beeton (née Mayson; 14 March 1836 – 6 February 1865), also known as Mrs. Beeton, was an English journalist, editor and writer. Her name is particularly associated with her first book, the 1861 work Mrs. Beeton's Book of Household Management. She was born in London and, after schooling in Islington, north London, and Heidelberg, Germany, she married Samuel Orchart Beeton, an ambitious publisher and magazine editor.

Isabella Mayson was born on 14 March 1836 in Marylebone, London. She was the eldest of three daughters to Benjamin Mayson, a linen factor (merchant) and his wife Elizabeth (née Jerrom). After a brief education at a boarding school in Islington, in 1851 Isabella was sent to school in Heidelberg, Germany, accompanied by her stepsister Jane Dorling. Isabella became proficient in the piano and excelled in French and German; she also gained knowledge and experience in making pastry. She had returned to Epsom by the summer of 1854 and took further lessons in pastry-making from a local baker.
