DNA Project How To

The most important first step in a DNA project is to set your goals. Randomly test individuals carrying the same surname, for instance, will not produce the targeted results needed if you are trying to answer particular questions about your ancestors.
The goals in our Forgey/ Forgy & Forgie DNA project are as follows:
  1. To identify all of the family branches using branch tags (branch specific marker mutations) or new unrelated lines through the discovery of families from different Haplo groups
  2. To extend our pedigrees by connecting branches 
  3. To find a possible ancestral locations in the Old World
To move towards those ends it's necessary to locate as yet untested family branches, and find a male carrying the name to test for that branch. Since testing is expensive it's important to stay focused on our goals.
I found the colorized group Y DNA charts to be the most useful when analyzing results. The color coding of the mutations tells you how far away from the modal (or common result) that person's marker was, minus is blue; plus is pink. In order to see the color coding you have to set up subgroups on the subgroup page, then place each person in a subgroup. I also found the marker title coloring to be useful. Red background markers are fast moving markers, and change often.
Our project is now in the process of testing 3 men to find out whether they are related to the other testers, and they are all from different branches. All of the first phase testers were related.  
I made the video above so I can remember everything I learned over the last few years. If anyone has any corrections or useful tips please share them.
