If you take his thread title as it is, it would be impossible to know who the first French American was. First of all, it would have to be an American born from French parents at a time when America was an actual political entity instead of a loose affiliation of colonies. Obviously, after the states were unified in the Declaration of Independence, and more formally under the Articles of Confederation and later on, the constitution, would be the time period. You could point to the Acadians who were banished to New Orleans, but that wasn't a part of America at the time, and New Orleans wasn't acquired until 1803. Can't count Canada because that's not America. You'd have to look into some Frenchman who came to the US after the states were brought together...Shit's confusing, but if you go by your standard, it makes it a lot easier.
