You know what they say. Location is everything. And not just in real estate. To research your family tree you first have to know where to look. Since the majority of genealogical and historical records are organized and maintained by locality, you'll need to know where your ancestors lived to access the records. Not just where they were born or died, but all the places they lived in between. Sometimes this is easy, but you'll often run across situations where a family disappears from the records. Where do you look then?
