Well, I read that they once called him "“Old Hickory” for a nick name.
He was actually the The first Irish-American president. Another funny fact is that North Carolina and South Carolina claim him as one of their own (birth place). Jackson even killed a man in a duel once in his life time, I am not 100% on the year, or who he killed but I read a novel about the occurrence. One of the most funniest facts about Andrew Jackson is that hated the idea of paper money...LOL...He is featured on the 20$ bill.
