Louisiana Creole expert Jari Honora has traced Prevost's ancestry to the Black community of New Orleans. His maternal ancestors lived in the Crescent City before migrating to Chicago in the early 20th century, Honora said.
Leo XIV is not known to have publicly commented having African ancestry, which is part of a mixed heritage that also includes French, Italian and Spanish roots. According to the U.S. Census, Prevost's mother, the late Mildred Martinez, was the mixed-race daughter of Black property owners, the Haitian-born Joseph Martinez and New Orleans native Louise Baquié, a Creole.
As such, Leo XIV could be considered the first Black pope in the history of the Catholic Church, though it is unclear how he identifies racially.
