Noting your ancestors’ locations chronologically can lead you to other records created in a particular time and place. Spreadsheets and word processors can help you create timelines with dates, addresses, and sources. Use these tools to note record gaps and ancestral migrations. Compare these chronologies with those of related families. By looking at where and when your ancestors lived at a particular time, and investigating circumstances in an area around the time of moves, you can gain a deeper understanding into what was happening in their lives and add depth to your family history.
