Healing is the basis of belief in San Lázaro, a popular saint among Cubans, Cuban-Americans, and other Latinx peoples. Stories about healing, received through faith in San Lázaro, are typically passed on through family members, rendering them genealogical narratives of healing. In this photo essay, the author draws on her maternal grandmother’s devotion to San Lázaro and explores how other devotees of this saint create genealogical narratives of healing that are passed down from generation to generation. These genealogical narratives of healing function as testaments to the efficaciousness of San Lázaro’s healing abilities and act as familial avenues through which younger generations inherit belief in the saint. Using interview excerpts and ethnographic observations conducted at Rincón de San Lázaro church in Hialeah, Florida, the author locates registers of lo cotidiano, the everyday practices of the mundane required for daily functions and survival, and employs arts-based methods such as photography, narrative inquiry, and thematic poetic coding to show how the stories that believers tell about San Lázaro, and their experiences of healing through faith in the saint, constitute both genealogical narratives of healing and genealogical healing narratives where testimonies become a type of narrative medicine.
