Margarito Flores García was a Mexican Catholic priest born in 1899 in the state of Guerrero. After growing up in a poor family and working in the fields, he entered the seminary at age 15. He was ordained in 1924 and served as a vicar in Chilopie. During the Mexican Revolution, he faced intense religious persecution, eventually being sent to minister in Atenango del Río, where he was killed by government forces in 1927.
