Bc Tyson is so freakin smart

I was talking to a friend of mine about my heritage. I said I was more than a quarter Irish but less than half. So he proceeded to figure out the math for me.
5/16 = Irish
4/16 = Swedish
4/16 = Dutch
2/16 = English
1/16 = Scottish

This means on my father's side his father is full Swedish and his mother is full Irish. On my mother's side her father was full Dutch and her mother had one parent who was all English and one who was Scottish and Irish. Im guessing the math is right. lol
