Absolutely. Well to a degree at least. My minor is in the classics, which is a direct result of my education. Specifically because of the amount of time spent on the Old Testament and greek myths.
I have a genetic predisposition towards historical geekness as DH likes to tell me. Most of my Dad's side of the family are history nerds. I can tell you my focus on European history is because I had better Euro teachers than American history teachers. They made it so exciting and interesting and we spent a lot more on it than public school kids because our requirements were stricter and didn't have to worry about budget cuts dictating class size and student grouping.
I had the standard American history program pretty much every kid around here has and it was unbelievably boring. If I decided to go with a graduate degree in US history, I would specialize in the colonial period, westward expansion or maritime history (Specifically the privateers and whalers). That would be because of personal interest developed outside of school.
Right now my focus is on Medieval History - particularly the plague, Reformation, and Hundred Year's War. The Reformation part is because of my Catholic education.
