Gaudalupe, of Spanish origin, translates to 'Baptism of St. John the Baptist'. It's composed of the words 'gua', meaning 'gulf' or 'sea', and 'dalupe', referring to the Virgin Mary. This name gained popularity during the Spanish conquest of Mexico, where it was adopted by indigenous people. Gaudalupe is celebrated on December 12th, but not as a name day, rather in honor of Our Lady of Guadalupe, an iconic figure in Mexico and Latin America.
The name Guadalupe appears to have had its highest popularity during the mid-20th century, with a noticeable peak in the late 1950s. However, it's interesting to note that there was a significant gap of nearly two decades between the first recorded birth and the next one.
