I finally got curious and looked it up:
Claudia Sheinbaum Pardo was born on 24 June 1962 in Mexico City, within a Mexican Jewish family.[11][12] She is the second child of chemist Carlos Sheinbaum Yoselevitz and biologist Annie Pardo Cemo.[13][14]
Carlos Sheinbaum was of Ashkenazi Jewish descent. His father, Chone Juan Sheinbaum Abramovitz,[15] had emigrated from Lithuania in 1928, becoming a jewelry merchant and a member of the Mexican Communist Party. Annie Pardo is from a Sephardi Jewish family who arrived in Mexico in 1946, after fleeing from the persecution of Jews in Bulgaria during World War II.[16] Pardo became the first Sephardic woman to be an academic at the Instituto Politécnico Nacional.[15][17]
Sheinbaum's parents were actively involved in Mexican left-wing circles during the 1960s, participating in protests, workers' movements, and student uprisings.[18]
Sheinbaum has two siblings. Her older brother Julio is a physicist[19] and physical oceanography researcher at CICESE.[20] Her younger sister Adriana is a teacher[21] who lives in the United States and is married to film director Rodrigo García Barcha
No Latino ethnicity in her blood stream - interesting -- but then, Peru, had a Japanese leader also.
