Jeremiah Dixon (died 1777, Durham, Durham, Eng.) was a British surveyor who, working with fellow surveyor Charles Mason, established the boundary between Maryland and Pennsylvania, known since as the Mason and Dixon Line.
All that is true but still, in the life of today 'Dixie' is kind of a stripper name. I would not name a child with carrying all that history.
Even so, there are thousands of people in America who are named Robert E. Lee.
