Isabel González (May 2, 1882 – June 11, 1971) was a Puerto Rican activist who helped pave the way for Puerto Ricans to be given United States citizenship. As a young unwed pregnant woman, González had her plans to find and marry the father of her unborn child derailed by the United States Treasury Department when she was excluded as an alien "likely to become a public charge" upon her arrival in New York City. González challenged the Government of the United States in the groundbreaking case Gonzales v. Williams (192 U.S. 1 (1904)). Officially the case was known as Isabella Gonzales, Appellant, v. William Williams, United States Commissioner of Immigration at the Port of New York No. 225, argued December 4, 7, 1903, and decided January 4, 1904. Her case was an appeal from the Circuit Court
