Margaret Thomas

Margaret Thomas (born Margaret Cook; 23 December 1842 – 24 December 1929) was an English-born Australian travel writer, poet and artist. Thomas was born at Croydon, Surrey, daughter of Thomas Cook, shipowner. Her date of birth is sometimes cited as 1843 and she was herself inconsistent about both her age and date of birth. It has also been discovered that she was originally named Margaret Cook and only later changed her surname to her father's first name.

Between 1868 and 1880, Thomas exhibited her paintings (mostly portraits) at the Royal Academy. Thomas' portraits of Charles Summers and Sir Redmond Barry, are held by the State Library of Victoria, Melbourne.
