Print A new horror anthology TV series, “Them: Covenant,” is making news for its grisly depictions of violence against a 1950s Black family in their new home in the then-white city of Compton. Without the supernatural elements, the decades-long stories of Black people trying to take up residence in Los Angeles County’s white neighborhoods are more than scary enough. L.A. didn’t start out that way. Of the 22 adults among the the first settlers, who set up housekeeping and created Los Angeles in 1781, 10 had African ancestry. And the last governor of Mexican-ruled California, Pio Pico, was of mixed race.
