There is nothing in the novel to suggest that the name has any significance beyond mere convenience. At the time, Jane explains her use of the alias by saying, "Anxious as ever to avoid discovery, I had before resolved to assume an alias," and in fact the name only appears four times in the novel. But Jane assumes the alias to mark a difference between her life with Rochester and whatever is to come. "Elliott" is an ordinary name, and her life with the Rivers siblings is an ordinary life, compared to the drama of life at Thornfield. In a sense, then, Jane Elliott is a different person than Jane Eyre; "Eyre" is an uncommon name, and "Jane Eyre" is (according to Rochester) a kind of magical creature, a "sorceress" or an "elf." It is significant that it is Jane Eyre, not Jane Elliott, who inherits the money. Jane Elliott might have gone off to India with St. John, but Jane Eyre finds it impossible.
