re my query about the name of Bernice Johnson Reagon and Cordell Reagon's daughter Toshi, it does seem probable that she was named for Toshi Seeger. Ken Miles wrote on a Facebook discussion, "Pete and Toshi helped the Freedom Singers a lot. Bernice Johnson Reagon spent time at the Seeger home in Beacon and eventually named her daughter Toshi. And Toshi Seeger booked the Freedom Singers on a tour of colleges throughout the U.S."
