Compiling a family history is more than just recording facts on a chart. Read about the places where your ancestors lived. What was happening that caused them to leave their county or move to Minnesota or move from Minnesota to somewhere else? What were their lives like?
Check local, county, and state histories, as well as church and synagogue histories. These resources can provide background on your family's life in Minnesota or wherever they settled.
Family histories of other families from the same area may have helpful information.
