:If the term French-American is not often used, why the heck is Wikipedia ought to frequent its usage? In any case, check out List of French Americans. Perfectly fine and perfectly sourced under Wiki policy. Sure, some people who are at most "ethnically half French" are excluded, but so what? As for Louis-Dreyfus, yes, her father was born in France but his mother was American. According to the article, he considered himself "American" too. If you have a source that said he was French, you could list him under French Americans if he was notable enough. As for Louis-Dreyfus herself - zero reason to put her under French-Americans if no source has called her that. Why would we? She's probably not "ethnically French" at all and I doubt she considers herself French American, so what's the big loss?
