The first wave of San Guillermo immigrants to America came in the early-1900s. San Guillermo natives living in California maintain their cultural heritage by hosting a gathering on Memorial Day in celebration of feast of patron saint San Isidro Labrador. Most San Guillermo natives live in the metropolitan areas of Los Angeles and San Francisco, and the feast is alternately celebrated in both cities since its conception in 1979.
