Tracing your family history is a continuous learning experience. In order to find our ancestors, we must learn about many record types—why they were kept, what they contain, and where to find them. We learn history, geography, legal, medical and antiquated terms; and possibly even a foreign language or two. We learn about libraries, archives, courthouses, online resources, and anyplace that may house the slightest clue to our ancestry. Fortunately, the information age has been good to family historians. Collections like those in this category bring a huge variety of reference materials to our computer screen.
