Agustín Pío Barrios (also known as Agustín Barrios Mangoré. May 5, 1885 - Aug 7 1944), an eminent Paraguayan guitarist and composer, was born May 5, 1885, in the department of Misiones, Paraguay and died August 7, 1944 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. Also, several biographers and authorities present convincing documented evidence that Barrios was born, instead, in the nearby town of Villa Florida, Misiones, situated on the Tebicuary River some 30 km north of San Juan Bautista.
