The document summarizes the immigration experiences of the Contreras and Urita families from Mexico to California in the early-to-mid 20th century. Both families came from Mexico as part of the fourth wave of immigration, with the Contreras family from Tijuana and the Urita family from Juarez. They came to California for work, finding jobs in a factory but earning low wages. Both families struggled financially when first settling in apartments and housing complexes. Over time, religious beliefs brought the families together, as the Contreras family introduced Mormonism to the Urita family.
