A detailed chronology is now at your finger tips. Use it wisely!
Be sure that you have detailed documentation for each item discovered in Step 2.
Now comes the fun part. [At least for those who still like to color.]
Use the colored "Hi-Liters" to make a color coding system for your notebook.
Yellow = historical information.
Blue = geographic items.
Pink = dates.

Rule in and rule out is part of the process.
Keep up the good work!
