Maps, Atlases & Gazetteers - Maps are an invaluable part of family history research, especially if you live far from where your ancestor lived. Because political boundaries often changed, historic maps are critical in helping you discover the precise location of your ancestor's hometown, what land they owned, who their neighbors were, and more.
