Who is Mary Carmichael? Is she important?

      "Here then was I (call me Mary Beton, Mary Seton, Mary Carmichael or by any name you please — it is not a matter of any importance) sitting on the banks of a river a week or two ago in fine October weather, lost in thought." Who are Mary Beton, Mary Seton, and Mary Carmichael? Since Mary Carmichael comes up again toward the end of Virginia Woolf's A Room of One's Own, I decided to do some research into the names to see if they are at all relevant, or were chosen by Woolf at random.
      The characters are from a ballad entitled "The Four Marys". Woolf mentions three of the Marys in the ballad, only ignoring the narrator of the poem, Mary Hamilton. Mary Beton is the narrator in Woolf's essay. I think that Woolf used Beton as her narrator so that she could detach herself from the essay to write it more effectively, but why did she use all these Marys? I think this question is answered by looking at Woolf's character Judith Shakespeare, who becomes trapped in a life that is "imposed on her", the life of a woman. This is the story of the Marys, too. Woolf sees all five women as powerless and treated as inferiors to men. Whether she intended for readers to understand the connection or not, I interpreted it as Woolf trying to show that she was not alone in her ideas and that other women stood with her.
      "She had — I began to think — mastered the first great lesson; she wrote as a woman, ‘but as a woman who has forgotten that she is a woman, so that her pages were full of that curious sexual quality which comes only when sex is unconscious of itself." I think this is the most important part about the Marys. Through Woolf's essay, I did start to see some things differently, but it was this part where I actually agreed with her on something. I think that statement about the imaginary book by Mary Carmichael really shows equality between the genders.
      In society today, people in general are very quick to judge on whether something/someone is too feminist or too anti-feminist. The happy medium, I believe, would be Mary Carmichael (as the author of the book Woolf's narrator was reading). On the feminist side in modern culture, we have characters in the media like Rory Gilmore (from Gilmore Girls) who graduated valedictorian, studied at Yale, and turned down marriage because she didn't want to be tied down. Characters like Rory are too few in the media. Instead, we've had characters like Blair Waldorf of Gossip Girl (who's goal in life was to marry a prince), Lauren Conrad of The Hills (whose entire life revolved around having a boyfriend), and Snooki from Jersey Shore (who is quoted saying "I want to marry a guido. My ultimate dream is to move to Jersey, find a nice, juiced, hot, tan guy, and live my life.") We need more in the media of characters like the women in imaginary Mary Carmichael's book. Though Virginia Woolf came before Snooki, Lauren Conrad, and Blair Waldorf, I think that she would agree about having some books or television shows where "sex is unconscious of itself" through the directors and authors.
