Her fourth husband, Alonso de Grado, soon died and Isabel, about seventeen years old, was widowed for a fourth time. Cortés took her into his household and she soon became pregnant. He quickly married her to another associate, Pedro Gallego de Andrade, and the child, christened Leonor Cortés Moctezuma (Isabel also had a half-sister named Marina or Leonor Moctezuma) was born a few months later. According to Spanish sources, she refused to recognize the child, who was placed in the care of Juan Gutiérrez de Altamirano, another close associate of Cortés. Cortés however accepted the child as his own and ensured that she was brought up well and received an inheritance from his and Doña Isabel’s estate.
