It doesn't make sense to me that they would make Stan a great uncle when they could just make him a grandfather. He's based off of Alex Hirsch's grandfather after all. Great uncle is just such a weird specification. It'd make just as much sense if they made Stan their grandfather. Unless there was a specific reason they didn't want to. Grandfather is more closely related. Dipper and Mabel's parent (whichever one is related to Stan) would know its own father better than its uncle, especially if there is a huge age difference between Stan and the grandfather. Thus an uncle is more mysterious.
