Lilian Randolph, whose given name was Castello Sanders, was in It's a Wonderful Life!, and also in Mildred Pierce, among a bunch of both "race" and Hollywood movies, radio, and TV.
Ketanji, whose name sounds like a fictional Japanese temple (化炭寺), needs to learn more about the history of "her people" than this honkey cracker, who sees Randolph as part of the history of the American people.
I wonder if Kentanji is her given name. I doubt it. My son’s mother in law was named Rose, but she changed it as an adult after having one kid. It’s a very African sounding name now. I think she feels more like her own self using her African name.
