What's the difference between a Family Tree and a Family History?
Family History is the research that goes behind compiling a Family Tree. It has been defined separately to Genealogy for what you might call snobbish reasons. Genealogy has been seen as this ancient pursuit of heraldic links and pedigrees. Family History has been seen as more of an amateur pastime or hobby. Essentially, it's exactly the same practice of research, and both will have the Family Tree. It's just that Family Historians tend to build a Family Tree, and Genealogists build pedigrees.
