As one gathers information about an ancestor, many types of documents are discovered – birth, marriage, and death records, land records, letters, Bibles, photos, etc. How is one to keep track of it all?
An Excel (or equivalent) spreadsheet is a good way to organize the information by date. Type in the document/artifact in one column, and the date in the next column. Then, sort by the date. Now everything is in chronological order – now it is known what happened in the correct order! And, this is very important!
