Coretta was the name of Martin Luther Kind’s wife IIRC. Ayers was using a classic (in his mind) “black” name. More mythology....It’s a very unusual name, never read or heard of it attached to any other human.
You’re spot-on as usual imo. There’s Ayres needing a ‘classical’ name for a negro girl-child, and what flashes through his mind but Coretta!
But as every lie has an iota of truth - it’s not hard to understand where this one came from. It would have been Ayres himself who was the bully, it’s an incident he remembers from his own childhood.
The class photograph must have come to light after the book was written. He’s so smart he’s outsmarted himself on numerous occasions. He must have thought Hawaii was full if white people...or that only whites sent their children to Punahou and zero was an anomaly.
