On February 2, 1848, with the stroke of a pen, Nicolás de Jesús Romero, Francisca Pacheco, (Rodolfo’s great-grandparents) and José de Jesús Domínguez and María Concepción Gonzales, (Amelia’s grandparents) became U.S. Citizens. The signing of the Treaty of Guadalupe Hidalgo, meant that the United State extended its borders to include more than 100,000 former Spanish subjects and Mexican citizens. They brought with them a culture that was different from that of traditional European immigrants.What Nicolas, Francisca, José, and Mariá didn’t know was that they had become foreigners in their native land, which inevitably led to misunderstandings and conflict.
