[3] She was a fifth-generation Afro-Argentine, a descendant of African slaves brought over to the Río de la Plata during Spanish colonial rule.
[4] Her great-great-grandfather was a freedman who had served for Gregorio Aráoz de Lamadrid, from whom he took his name as it was the custom for freed slaves in early 19th-century Argentina.
[5] In the 1950s and 1960s, she formed part of the music group Las Mulatas de Ébano ("the Ebony Mulattas"), founded by her aunt, Tina Lamadrid.
[3][7] Lamadrid founded the NGO "África Vive" in April 1997, after collaborating with a group of researchers from the Inter-American Development Bank looking into the African roots of Argentine society.
[4] That November's "Afroargentinidad Month" celebrations, as well as the National Day of Afro-Argentines and Afro culture, were dedicated to Lamadrid's memory by the Government of Argentina.
