National Genealogical Society Basic Ancestor ChartA chart to fill in information about you, your parents, grandparents, and great-grandparents. You don't need to fill this all in before class, but doing as much as you can will be very helpful. There are a very limited number of recent records (i.e., after 1940) available online. The goal of completing this worksheet is to trace your family back to that point, or as near as you can get.
