Leonarda Gómez Blanco (1900 -?) was a Mexican teacher and early member of the Socialist Party of the Southeast. She served as the head of the Cultural Missions Program and Director of Education in both Campeche and Tlaxcala.
This name was borne by serial killer Leonarda Cianciulli, who killed three women and made their bodies into soup and teacakes. She sacrificed them because she believed they would protect her son Giuseppe.
Don't forget about the Mexican usage! Leonarda Emilia Martínez was a Mexican criminal known as La Carambada who wore men's clothing and famously showed them her breasts before leaving, to humiliate them with the knowledge that they had been robbed by a woman.
