Isobel Graham Finlayson (January 20, 1811 – August 22, 1890) was an English-born diarist and artist.
Her diary is one of the few accounts written by a European woman about travel associated with the North American fur trade.
[1] The daughter of Geddes Mackenzie Simpson, a London merchant with close ties to the Hudson's Bay Company, and Frances Hume Hawkins, she was born Isobel Graham Simpson in London.
[1] In 1838, she married Duncan Finlayson, the governor of Assiniboia which was also known as the Red River Colony.
Her husband left for Rupert's Land in the spring of 1839 but, because of her health, she did not follow him until the summer of that year.
