Ирапуато
Siqueiros was born in Chihuahua in 1896, the second of three children. He was baptized José de Jesús Alfaro Siqueiros. His father, Cipriano Alfaro, originally from Irapuato, was well-off. His mother was Teresa Siqueiros. Siqueiros had two siblings: a sister, Luz, three years elder, and a brother "Chucho" (Jesús), a year younger. David's mother died when he was four and their father sent the children to live with their paternal grandparents. David's grandfather, nicknamed "Siete Filos" ('seven knife-edges'), had an especially strong role in his upbringing. In 1902, Siqueiros started school in Irapuato, Guanajuato.
