I'd argue that Kentucky should be green. Sure the 'y' becomes an 'i', but it's still pronounced like Kentucky+-an so the difference is purely orthographic.
And changing a final 'y' to 'i' is extremely common when adding a suffix. (cf. happiness, beautiful, angrier)
Having grown up there, I always liked Connecticutian as a serious one, but also accepted is Nutmegger (it's the nutmeg state) and best jokey name is Connecticunt (pairs well with our neighboring Massholes)
Yeah but. I lived in Indiana for a long time and most people just say Indianan. Hoosier is more of a Midwest thing. I'm from Arkansas, and that and Florida is a little odd. It's pronounced differently than the state is.
Most people from where? Everyone in Indiana says Hoosier. Maybe it is a Midwest thing, but I don't know how I'd react if someone called me an Indianan. It doesn't even sound correct (admittedly, at least 20% of these sound really awkward).
I had an American history teacher in high school who was adamant we weren't Arkansan because fuck Kansas (paraphrased). He said we were Arkansonian. It doesn't seem to have caught on.
...tejanos around here can be of any ethnicity: it's considered a cultural identity (not unlike hispanic or latino) for folks with deep roots in the original regional melting-pot but it's not synonymous with the texian or broader post-revolutionary texan population...
There's a weird sect of white Texans who call themselves Tejanos as a constructed cultural identity that has nothing to do with historical Tejanos.
Very much the kind of people who will sit in a truck stop diner for eight hours a day explaining to anyone who will listen that Texas is the only state that can legally secede because blah blah blah the republic blah blah Texas is actually its own nation, technically blah blah blah the Texas Rangers actually outrank the feds because precedence blah blah blah
I have family pretty much all over the eastern seaboard, and elsewhere in smaller numbers.
Most the these are accurate overall.
However! There is another term for folks from the Carolinas, Carolingians. It seems to have faded from common use, but several of my cousins around my age were still seeing it in textbooks.
It was also applied to North and South Carolingians separately, not just to all people in the Carolinas as a whole.
