The
University of Pennsylvania Law School rejected Kilgore's application in 1871. She attempted to buy individual tickets to attend lectures. Sometime later, she sent her husband to purchase the lecture passes, but the Board of Trustees informed her that even if she attended every required lecture and passed all of the examinations, they would not guarantee that she would earn a diploma. After studying privately, Kilgore asked to take the bar exam in 1873 and 1874, but was refused. She obtained immediate admission to the Orphan’s Court of Philadelphia, but she had to engage in yet another lobbying campaign to gain admittance to practice before the
Pennsylvania courts of common pleas in 1884, the
Supreme Court of Pennsylvania in 1885, and the
U.S. Supreme Court in 1890. Active in the
women's suffrage movement, Kilgore sought to vote at city and county elections in 1871. She was ruled against and appealed to the full state supreme court, which affirmed the ruling against her. She published a pamphlet with her argument before the state supreme court, titled
Woman Suffrage. The Argument of Carrie S. Burnham, which included the opinion of the man who originally ruled against her,
George Sharswood. Kilgore served on the advisory committee and as a vice president of the
National Woman Suffrage Association and spoke at national suffrage conventions. == Personal life and death ==
