(Unless, of course, it isn't.)
I have only just remembered -
From time to time, mostly in my teens, but extending into my 20s, in filling out forms, (nothing official, that I can recall,) I would write "white Afro-American," or "African American,"or "mixed" when asked for "race," based on the fact that there was a (very spurious,) family legend of a Hiberno-Norman antecedent who had a French crusader ancestor who took the long way home and brought back a wife from north Africa.
Girls who read too many novels are always looking for ways to romanticize their own saga.
(And look at what happened to poor Emma Bovary!)
