The fort was given its name by Sir George Simpson, governor of the Northern Department of the Hudson’s Bay Company in honour of his wife, Lady Frances Ramsay Simpson. As there is a recorded armorial bearings for Lady Frances’ branch of the Ramsay family, Clarenceux King of Arms in London approved use that the device. The device chosen was the unicorn’s head, with a collar bearing a Canadian maple leaf.
