Who was Annie Oakley in the book Buffalo Girls?

Buffalo Girls is a novel written by Larry McMurtry and published in 1990. It tells the story of many real-life notable figures of the American West as the time of the Wild West comes to an end. This story is largely told through the letters of well-known frontierswoman Calamity Jane. One of the characters that she describes in these letters is her fellow Buffalo Bill's Wild West performer, the legendary sharpshooter Annie Oakley.
In the novel, Buffalo Bill's Wild West show is depicted as being a way in which these big figures of the Wild West can recreate their experiences and slowly adapt to the new ways of living, which are more lawful and peaceful. Annie Oakley is known to have been a talented exhibition shooter and celebrity. Her and Calamity Jane are often grouped despite their considerable differences. Though they both were famous women of the time, their talents and general reception were different. Annie Oakley was typically more respected than the wilder, suspected fibber Calamity Jane; though Calamity Jane remained quite well-liked, even as her alcoholism worsened. Comparing and contrasting these two characters is a fantastic way to analyze them as individuals!
