FWIW, based on my grandmother's nine grandchildren, only two have married white people and those two were probably the most white adjacent out of all of us as they grew up in the Upper West Side in Manhattan. One cousin married a FBA, another married a fellow Caribbean. And so far, four great grandchildren are products of FBA relationships, one is FBA/Hispanic, and two are mixed race.
From what I've seen, we're melting into the FBAs.
