Judging by your family, would you be Pureblood, Half-Blood or Muggle-born?
The only way I can think to answer this is through my heritage. Haha. I wouldn't really be bothered if I was any of the above. Anyway, this is how I'm going to do it. I'm Welsh. I'm not 100% Welsh though. I was born in Wales but I have Irish in my family via my grandfather. This would make me half-blood because I'm not pure Welsh. So all I'm going to do is transfer that to wizarding terms and become a Half-Blood. One muggle parent and one pureblood. I don't even know if this is making any sense but I didn't know how else to do it!
