Agustín Pío Barrios (also known as Agustín Barrios Mangoré, May 5, 1885 – August 7, 1944), an eminent Paraguayan guitarist and composer, was born in the department of Misiones, Paraguay and died in San Salvador, El Salvador. It has been generally accepted that the guitarist was born in San Juan Bautista in Misiones, however, there is no definitive proof of this as his baptismal document found in the book of registries in the cathedral in San Juan Bautista does not state his precise place of birth.
