1907–1924: Family and childhood thumb|right|Kahlo (on the right) and her sisters Cristina, Matilde, and Adriana, photographed by their father, 1916 Magdalena Carmen Frida Kahlo y Calderón was born on 6 July 1907 in Coyoacán, a village on the outskirts of Mexico City. Kahlo stated that she was born at the family home, La Casa Azul (The Blue House), but according to the official birth registry, the birth took place at the nearby home of her maternal grandmother. Kahlo's parents were photographer Guillermo Kahlo (1871–1941) and Matilde Calderón y González (1876–1932), and they were thirty-six and thirty, respectively, when they had her. Originally from Germany, Guillermo had immigrated to Mexico in 1891, after epilepsy caused by an accident ended his university studies. Although Kahlo said her father was Jewish and her paternal grandparents were Jews from the city of Arad, this claim was challenged in 2006 by a pair of German genealogists who found he was instead a Lutheran. Matilde was born in Oaxaca to an Indigenous father and a mother of Spanish descent. In addition to Kahlo, the marriage produced daughters Matilde (c. 1898–1951), Adriana (c. 1902–1968), and Cristina (c. 1908–1964). She had two half-sisters from Guillermo's first marriage, María Luisa and Margarita, but they were raised in a convent.
