According to indications equivalent to proofs in the absence of any positive record, from such respectable forebears descended Fray Bartolomé de Las Casas, who was born in Seville, in 1474. He himself speaks of Seville as his native city, and the popular tradition, which fixes the ancient suburb of Triana as his birthplace, was recognised in 1859 by the municipality of Seville assigning the name of Calle del Procurador to one of the streets of Triana, in honour of the Bishop, whose proudest title was Protector (or Procurador) General of the Indians. In his voluminous writings, which teem with information about the men and events of his times, the references to his own family history are infrequent and imperfect, so that from his own records of his life, very little is to be gleaned concerning it. His father’s name is variously given by different writers as Alonso, Antonio, and Francisco, while he himself states(1) that he was named Pedro, thus contradicting all his biographers from Remesal, who was the first, down to Don Antonio Fabié, whose admirable _Vida y Escritos_, published in 1879, was the last important contribution on this interesting subject. Zuñiga, in his _Discurso de Ortices_, assumed that Alonso de las Casas and Beatriz Maraver y Cegarra of Triana were the parents of Fray Bartholomew, but in the _Anales de Sevilla_, a later work, Francisco is given as the father’s name. Neither Llorente nor Gutierrez, who has followed him, gives any authority for his affirmation that the father’s name was Antonio, while Quintana and Fabié accept Remesal(2) and name the father Francisco. The genealogy of the family furnished me by the dean of the Royal College of Heralds in Madrid shows the descent of Fray Bartholomew through his frather, named Francisco, from Alonso de Las Casas, “Señor de Gomez Cardeña, Veinticuatro de Seville, la Villa de Priego” in 1409, and his wife, Maria Fernandez Marmolejo. The children of this couple were Guillen, Isabel, Juan, Pedro, and Francisco, who is described in the genealogy as the father of Bartholomew. Pedro, whom Fray Bartholomew mentions as his father, is described as _Dean of Seville_, in which case his ecclesiastical state would exclude matrimony and legitimate issue.
