My family also had stories about how we are descendants of Cherokees, specifically Pocahontas and John Smith.

My Ancestry DNA doesn't show a lick of Native American, however, uploading my results to GEDMatch shows a very low percentage. Around 0.1% - which isn't enough for Ancestry to show.

What I find amazingly interesting is that, despite my paternal grandfather being "full blooded" Italian, my results show more Irish and Scottish DNA than it does Italian. I do have Irish and Scottish from both sides, my paternal grandmother has some in her family, even though her family claimed Dutch and German ancestry. It's interesting to see how much different ethnicities make up our DNA despite what our families tell us.

As far as wearing the kilt goes... I've had plenty of people ask me why I wear one if I'm Italian (I'm American, but OK). My answer is similar to yours. I hate pants, and kilts are terribly comfortable. I know some people are purists claiming you can't wear the kilt unless you have some Scottish in you, but those people are wrong.
