My mom's side is Irish & Scotch-Irish
My dad's side is German & Scotch-Irish
I usually tell people I'm Irish & German. The scotch-irish on either side is pretty minute, and a long time ago (like you trace back through the german 200 years to get there). I used to only be into the Irish culture. Then in hs I had the opportunity to travel to Europe, mainly Germany. And I
love it there and then got into that side of my heritage, too. I know more about the Irish side because that part of the family is always telling stories. The German side doesn't too much, but then one of my cousins last year researched all of this family history, and compiled a books she gave to all of our aunts/uncles. So I have a copy of that & it's got some interesting stuff in it.
My mom, brother & I also have a couple really distinct Native American features (in our jaw line & teeth structures.) My mom has always had dentists & even doctors ask her about it. Apparently there were some indiscretions in that side of the family (i.e. illegitimate children from Native Americans that were hushed up), and just a couple years ago my mom was contacted by a 1/2 cousin (or 1/4 cousin or something) that is *obviously* Native American & can even trace it a ways. So I have just a tiny bit of Native American, which I think is cool, but I don't really consider myself to be Native American unless I'm telling this long story about my heritage.
