Who called the march girls Little Women?

The term "Little Women" was popularized by author Louisa May Alcott in her novel of the same name, first published in two volumes in 1868 and 1869. The story follows the lives of the four March sisters—Meg, Jo, Beth, and Amy—during and after the American Civil War, portraying their growth from childhood to adulthood. While the phrase "little women" refers to their youth and development, it has since come to represent the themes of female identity and familial bonds in the novel.
